This is a collateral attack upon the death sentence by a Texas court of Johnny Paul Penry. With one exception all of the contentions advanced on Penry’s behalf are easily rejected. The exceptional contention is that Texas law did not permit the jury to consider, and to apply, all of Penry’s personal mitigating circumstances prior to reaching the verdict that mandated his death sentence. We are bound by superior *917authority to reject that contention, but we discuss the problem fully to demonstrate why it may merit further consideration.
I.
On the morning of October 25, 1979, Pamela Carpenter was brutally beaten, raped, and stabbed with a pair of scissors in her own home in Livingston, Polk County, Texas. She died a few hours later, but she was able to relay a description of her assailant to the first police officer on the scene and to the doctor in the hospital.
The description led two local sheriffs deputies to suspect Penry. They went to the house of Penry’s father, where Penry was staying. Penry denied any involvement but voluntarily agreed to go with the officers to the police station.
At the police station the officers and Penry were met by a number of other local law enforcement agents. They read Penry his Miranda rights and questioned him about a wound on his back. After being warned again, Penry signed a consent to search form. Everybody then went back to the Penry home to retrieve a shirt he had worn earlier that day.
Penry then accompanied the police officers to the scene of the crime. There Pen-ry, for the first time, stated that he had “done it.” He was immediately arrested, handcuffed, and read his rights again. He was brought back to the police station and taken before a magistrate. Penry was formally charged with capital murder. The magistrate read and questioned Penry about whether he understood his rights. Penry stated that he understood his rights and signed the warning forms.
Police Chief Bill Smith then questioned Penry after again warning him. Penry agreed to give a statement. Smith took the statement in notes and turned it over to his secretary to type. After the statement was typed, because Penry could not read, it was read to him in front of two non-police witnesses. That statement described the crime in detail, and Penry signed it.
Texas Ranger Cook took a second statement the following day. Again, the statement was read back to Penry in front of two non-police witnesses, and it contained the Miranda warnings and a statement that the rights were being waived. The second statement told of the crime in even more detail and contained confessions of Penry’s previous crimes.
These two statements formed the heart of the prosecution against Penry. The statements were consistent with the other evidence, including proof that Penry had been at Ms. Carpenter’s house once before, Ms. Carpenter’s statement about being raped and stabbed, the bloody scissors found at the scene, and the position of the victim’s clothing as described by the ambulance attendant. However, there was no physical evidence (blood, semen, fingerprints or hair samples) linking Penry to the scene of the crime.
At a competency hearing before trial, Penry was shown to have limited mental ability. He could not read or write, having never finished the first grade. His IQ indicated mild to moderate retardation. He had been in and out of a number of state schools. His relatives testified that he was beaten as a child and had behaved strangely as both a child and a teenager. Nevertheless, a jury found him competent to stand trial.
At the guilt/innocence phase of his trial, evidence of Penry’s limited mental capacity was reintroduced. There was disagreement among the three testifying psychiatrists whether Penry was insane: the defense psychiatrist opined that he was, but the state’s two psychiatrists disagreed. There was also disagreement over the degree of Penry’s mental limitation and the cause of the limitations. However, all of the psychiatrists agreed that Penry had mental limitations, whether caused by a birth trauma or by childhood environmental factors such as beatings and being locked in his room for extended periods of time. They also agreed that Penry’s problems manifested themselves, among other ways, in an inability to learn from his mistakes.
The jury rejected Penry’s insanity defense and found him guilty of capital murder. Tex.Penal Code Ann. § 19.03 (Vernon *9181974). The jury then answered “yes” to all three “special issues,” and Penry was sentenced to death. Tex.Crim.Proc.Code Ann. art. 37.071 (Vernon 1981 & Supp.1987). The Texas Court of Criminal Appeals affirmed the conviction and sentence. Penry v. State, 691 S.W.2d 636 (Tex.Crim.App.1985), cert. denied, 474 U.S. 1073, 106 S.Ct. 834, 88 L.Ed.2d 805 (1986).
II.
Penry argues that it would be cruel and unusual punishment to execute a mentally retarded person such as himself. He cites Ford v. Wainwright, 477 U.S. 399, -, 106 S.Ct. 2595, 2600, 91 L.Ed.2d 335 (1986), for the proposition that “idiots and lunatics are not chargeable for their own acts.” An identical claim has recently been rejected by this court. Brogdon v. Butler, 824 F.2d 338, 341 (5th Cir.1987). Penry’s claim is without merit.
Penry raises a number of issues regarding his two confessions. He first claims that they should have been suppressed because they were the fruit of an illegal arrest. A Fourth Amendment claim of illegal arrest is foreclosed in habeas if the state “provided an opportunity for full and fair litigation” of the claim. Stone v. Powell, 428 U.S. 465, 493-95, 96 S.Ct. 3037, 3052-53, 49 L.Ed.2d 1067 (1976). Recognizing the Stone bar, Penry argues that he did not have a “full and fair” suppression hearing. He claims that the state limited his investigator’s fees, that a police officer who testified at both the suppression hearing and trial lied at the suppression hearing, and that the state failed to provide him with one of his previous confessions. Penry’s claims are without merit. Penry does not point out what difference more investigator’s fees, or having his previous confession, would have made. The police officer’s testimony at the suppression hearing was not inconsistent with his trial testimony. We have made an “independent evaluation of the state court record” and are satisfied that Penry’s “opportunity to contest the introduction of incriminating evidence resulting from his arrest was not circumscribed.” Billiot v. Maggio, 694 F.2d 98, 100 (5th Cir.1982). Stone bars relitigation of the issue here.
Penry also argues that his confession was involuntary and that he did not voluntarily waive his Miranda rights. Most of Penry’s argument on both issues centers on his low intellect and inability to freely confess or waive his rights. However, “coercive police activity is a necessary predicate to the finding that a confession is not ‘voluntary’ within the meaning of the Due Process Clause of the Fourteenth Amendment.” Colorado v. Connelly, — U.S. -, -, 107 S.Ct. 515, 522, 93 L.Ed.2d 473 (1986). Similarly, "Miranda protects defendants against government coercion leading them to surrender rights protected by the Fifth Amendment; it goes no further than that.” Connelly, 107 S.Ct. at 524. We have carefully examined the record, as is our duty, see Miller v. Fenton, 474 U.S. 104, 106 S.Ct. 445, 88 L.Ed.2d 405 (1985) (ultimate question of voluntariness of confession subject to plenary review by federal habeas court), and can find no evidence of police misconduct that would taint the confessions or waiver of rights. Both the confession and waiver of Miranda rights were voluntary.
Penry also challenges the exclusion of one venireman for cause. Citing Wainwright v. Sykes, 433 U.S. 72, 97 S.Ct. 2497, 53 L.Ed.2d 594 (1977), the state argues that Penry procedurally defaulted on the issue. When the state court opinion is silent as to whether it used the procedural bar,
this Court will consider “whether the state court has used procedural default in similar cases to preclude review of the claim’s merits, whether the history of the case would suggest that the state court was aware of the procedural default, and whether the state court’s opinions suggest reliance upon procedural grounds or a determination of the merits.”
Ortega v. McCotter, 808 F.2d 406, 408 (5th Cir.1987) (quoting Preston v. Maggio, 105 F.2d 113, 116 (5th Cir.1983)). In the state habeas claim here, the only time that issue was raised, the state court simply denied the writ without an opinion. However, *919Texas has consistently applied a procedural bar to exclusion of veniremen without objection. Hawkins v. State, 660 S.W.2d 65, 82 (Tex.Crim.App.1983). Similarly, the state court was aware of the procedural bar in this case since the state raised the bar in its reply to Penry’s state habeas claim. Therefore, under the Preston test, the claim is barred if Penry failed to object to the exclusion at trial.
At trial, Penry’s counsel originally objected to the state’s motion to exclude the venireman for cause. However, after a number of attempts at rehabilitation, counsel withdrew his objection and the challenge for cause was granted. Penry argues that the attorney’s argument was not “an expressed withdrawal of the objection but a statement of resignation to the fact that the Court was going to grant the State’s challenge for cause in spite of the objection.” We disagree. Our reading of that part of the voir dire convinces us that counsel did expressly withdraw his objection. He did so “regretfully” because he wanted the juror but knew that the juror could not be rehabilitated. The Sykes bar precludes our consideration of the merits of the issue.
III.
A.
The jury rejected Penry’s insanity defense and found him guilty of capital murder.1 The Texas bifurcated statutory scheme then provides for the jury to decide the sentence by answering three “Special Issues”:
(1) whether the conduct of the defendant that caused the death of the deceased was committed deliberately and with the reasonable expectation that the death of the deceased or another would result;
(2) whether there is a probability that the defendant would commit criminal acts of violence that would constitute a continuing threat to society; and
(3) if raised by the evidence, whether the conduct of the defendant in killing the deceased was unreasonable in response to the provocation, if any, by the deceased.
Tex.Crim.Proc.Code Ann. art. 37.071(b) (Vernon 1981 & Supp.1987). If the jury unanimously answers “yes” to all three questions, the court must sentence the defendant to death. Tex.Crim.Proc.Code Ann. art. 37.071(c)-(e) (Vernon 1981 & Supp. 1987). Otherwise, the defendant must be sentenced to life imprisonment. Id. Here, additional evidence was introduced in the sentencing phase. The jury was then instructed, inter alia:
You are further instructed that in determining each of these Special Issues you may take into consideration all of the evidence submitted to you in the full trial of the case, that is, all of the evidence submitted to determine the guilt or inno*920cence of the defendant, and all of the evidence, if any, admitted before you in the second part of the trial wherein you are called upon to determine the answers to Special Issues hereby submitted to you.
The jury instructions then proceeded to list, without definition, the three special issues with names of the defendant and decedent inserted.
Penry objected to the jury charge. He complained that the court failed to define “deliberately,” “probability,” “criminal acts of violence” and “continuing threat to society.” He also objected that the court failed to instruct the jury to weigh aggravating and mitigating circumstances and failed to authorize a discretionary grant of mercy based on the existence of mitigating circumstances.
The objections were overruled and the jury answered “yes” to all three special issues. Penry was sentenced to death. On direct appeal, the Texas Court of Criminal Appeals rejected Penry’s objections to the jury charge. Penry v. State, 691 S.W.2d at 653-54. The court held that the words used in the special issues need not be defined because the jury could understand the words’ common meaning. Id. With respect to Penry’s argument on weighing of aggravating/mitigating circumstances, the court stated that
it has in effect been answered by the Supreme Court’s opinion in Jurek v. Texas, 428 U.S. 262, 96 S.Ct. 2950, 49 L.Ed.2d 929 (1976), upholding this State’s statutory scheme for imposing capital murder. Our statutory scheme allows for broad consideration of aggravating and mitigating factors. V.T.C.A. Penal Code, Sec. 19.03 ensures that imposition of the death sentence is not even a possibility if certain aggravating circumstances are not proven beyond a reasonable doubt by the State.
Defendants are allowed to present all possible relevant mitigating information at the punishment hearing, as part of the effort to aid the jury in answering the special issues.
Defense counsel is allowed to argue against the death penalty in general, or its imposition in the particular case at hand in light of all relevant mitigating factors. In sum, the Texas death penalty scheme passes constitutional muster despite failure to require the jury to find that aggravating factors outweigh mitigating ones.
Id. at 654.
The jury was allowed to hear all evidence that might mitigate the culpability of Pen-ry’s deeds or his person. The jury could then consider (i.e. think about) the bearing of all of the evidence, aggravating and mitigating, upon the ultimate question of whether Johnny Paul Penry should be put to death. If, however, that consideration should lead the jury to decide against the death sentence, how is the decision given effect and incorporated into the verdict? No interrogatory asks about that most crucial decision. Having said that it was a deliberate murder and that Penry will be a continuing threat, the jury can say no more. The court, following Texas law, ends the matter and orders death. It is difficult to see how this procedure accords with some of the Supreme Court’s writings on the Eighth Amendment’s mandate of individualized application of all mitigation along with aggravation in the sentencing decision. In order to explain our concern, we must look further at the Supreme Court’s writings on capital punishment.
B.
The Supreme Court, in Gregg v. Georgia, 428 U.S. 153, 96 S.Ct. 2909, 49 L.Ed.2d 859 (1976), laid the foundations for the post-Furman 2 era of capital punishment. The plurality3 in Gregg held that the Georgia *921capital punishment statute was constitutional. 428 U.S. at 207, 96 S.Ct. at 2941. That statute provided for a bifurcated trial with the guilt/innocence phase followed by a punishment stage. Id. at 195, 96 S.Ct. at 2935. At the punishment stage, the jury had to find at least one aggravating circumstance before it could impose the death penalty. Id. at 197, 96 S.Ct. at 2936. Additionally, at the punishment phase, the jury could consider any other aggravating or any mitigating circumstances before imposing either death or life imprisonment. Id.
Although the Court warned that “each distinct system must be examined on an individual basis,” id. at 195, 96 S.Ct. at 2935, two basic principles stand out. First, in order to pass constitutional muster, the sentencer’s4 discretion must be narrowed. That can be accomplished by the finding of aggravating circumstances either about the crime or the defendant involved. Second, the sentencer must consider the circumstances and the defendant involved. That is usually done through consideration of mitigating circumstances.
The other four cases decided on the same day as Gregg all involved application of the two basic principles. In Woodson v. North Carolina, 428 U.S. 280, 96 S.Ct. 2978, 49 L.Ed.2d 944 (1976), the Court struck down a North Carolina law that mandated the death penalty for “a broad category of homicidal offenses.” 428 U.S. at 287, 96 S.Ct. at 2983. The Court found that one of the statute’s “constitutional shortcoming[s]” was that it failed “to allow the particularized consideration of relevant aspects of the character and record of each convicted defendant before the imposition upon him of a sentence of death.” Id. at 303, 96 S.Ct. at 2991. Likewise, the Louisiana mandatory death penalty, even though it was considerably narrower than North Carolina’s and provided for jury instruction on lesser included offenses even if not warranted by the evidence, was, for similar reasons, found to be unconstitutional. Roberts v. Louisiana, 428 U.S. 325, 332, 335-36, 96 S.Ct. 3001, 3005, 3007, 49 L.Ed.2d 974 (1976).
The Florida statute was considered by the Court in Proffitt v. Florida, 428 U.S. 242, 96 S.Ct. 2960, 49 L.Ed.2d 913 (1976). That statute, similar to Georgia’s, required the sentencer (the judge with an advisory jury) to weigh eight enumerated aggravating circumstances against seven enumerated mitigating circumstances. Id. at 251, 96 S.Ct. at 2966. The Court found the statute constitutional since the aggravating factors serve to narrow the focus on the crime and the mitigating factors force the sentencer to “focus on the individual circumstances of each homicide and each defendant.” Id. at 252, 96 S.Ct. at 2966.
The Court, on the same day as Gregg, Proffitt, Roberts, and Woodson, considered the Texas statute at issue here. The Court first held that the Texas definition of capital murder in § 19.03 was the equivalent of finding “a statutory aggravating circumstance before the death penalty may be imposed.” Jurek v. Texas, 428 U.S. 262, 270, 96 S.Ct. 2950, 2956, 49 L.Ed.2d 929 (1976). The Court then addressed the issue of mitigating circumstances;
But a sentencing system that allowed the jury to consider only aggravating circumstances would almost certainly fall short of providing the individualized sentencing determination that we today have held in Woodson v. North Carolina to be required by the Eighth and Fourteenth Amendments. For such a system would approach the mandatory laws that we today hold unconstitutional in Wood-son and Roberts v. Louisiana. A jury must be allowed to consider on the basis of all relevant evidence not only why a death sentence should be imposed, but also why it should not be imposed.
Thus, in order to meet the requirement of the Eighth and Fourteenth Amend*922ments, a capital-sentencing system must allow the sentencing authority to consider mitigating circumstances. In Gregg v. Georgia, we today hold constitutionally valid a capital-sentencing system that directs the jury to consider any mitigating factors, and in Proffitt v. Florida we likewise hold constitutional a system that directs the judge and advisory jury to consider certain enumerated mitigating circumstances. The Texas statute does not explicitly speak of mitigating circumstances; it directs only that the jury answer three questions. Thus, the constitutionality of the Texas procedures turns on whether the enumerated questions allow consideration of particularized mitigating factors.
The second Texas statutory question asks the jury to determine “whether there is a probability that the defendant would commit criminal acts of violence that would constitute a continuing threat to society” if he were not sentenced to death. The Texas Court of Criminal Appeals has yet to define precisely the meanings of such terms as “criminal acts of violence” or “continuing threat to society.” In the present case, however, it indicated that it will interpret this second question so as to allow a defendant to bring to the jury’s attention whatever mitigating circumstances he may be able to show:
In determining the likelihood that the defendant would be a continuing threat to society, the jury could consider whether the defendant had a significant criminal record. It could consider the range and severity of his prior criminal conduct. It could further look to the age of the defendant and whether or not at the time of the commission of the offense he was acting under duress or under the domination of another. It could also consider whether the defendant was under an extreme form of mental or emotional pressure, something less, perhaps, than insanity, but more than the emotions of the average man, however inflamed, could withstand. 522 S.W.2d, at 939-940.
Id. at 271-73, 96 S.Ct. at 2956-57 (citations and footnotes omitted). The Court then concluded:
Thus, Texas law essentially requires that one of five aggravating circumstances be found before a defendant can be found guilty of capital murder, and that in considering whether to impose a death sentence the jury may be asked to consider whatever evidence of mitigating circumstances the defense can bring before it. It thus appears that, as in Georgia and Florida, the Texas capital-sentencing procedure guides and focuses the jury’s objective consideration of the particularized circumstances of the individual offense and the individual offender before it can impose a sentence of death.
Id. at 273-74, 96 S.Ct. at 2957 (footnotes omitted).
We have no doubt that the Texas statute sufficiently narrows the circumstances in which death is imposed. Instead, we are concerned with Gregg’s second part; the individual consideration of the circumstances of the crime and the character of the individual. That law has not been stagnant since Gregg. The Supreme Court has developed what is meant by individualized consideration.
Two years after Gregg, the Court considered an Ohio capital punishment statute that required the death penalty unless one of three narrowly drawn mitigating circumstances was present. Lockett v. Ohio, 438 U.S. 586, 593-94, 98 S.Ct. 2954, 2959, 57 L.Ed.2d 973 (1978). The Court found the statute unconstitutional, holding
that the Eighth and Fourteenth Amendments require that the sentencer ... not be precluded from considering, as a mitigating factor, any aspect of a defendant’s character or record and any of the circumstances of the offense that the defendant proffers as a basis for a sentence less than death.
Id. at 604, 98 S.Ct. at 2964-65 (emphasis in original).
In Eddings v. Oklahoma, 455 U.S. 104, 115, 102 S.Ct. 869, 877, 71 L.Ed.2d 1 (1982), the defendant, 16 years old at the time of the murder, offered evidence of his trou*923bling family background and his emotional disturbance. In sentencing Eddings to death, the trial judge stated that “ ‘in following the law,’ he could not ‘consider the fact of this young man’s violent background.’ ” Id. at 112-13, 102 S.Ct. at 876. The Court found that the sentencing violated the rule in Lockett:
Just as the State may not by statute preclude the sentencer from considering any mitigating factor, neither may the sentencer refuse to consider, as a matter of law, any relevant mitigating evidence. In this instance, it was as if the trial judge had instructed a jury to disregard the mitigating evidence Eddings proffered on his behalf. The sentencer, and the Court of Criminal Appeals on review, may determine the weight to be given relevant mitigating evidence. But they may not give it no weight by excluding such evidence from their consideration.
Id. at 113-15, 102 S.Ct. at 876-77 (footnotes omitted).
After Eddings, the Court has made clear that the range of mitigating factors that must be considered is very wide. For example, in Skipper v. South Carolina, 476 U.S. 1, 106 S.Ct. 1669, 90 L.Ed.2d 1 (1986), the Court reversed a death sentence because the trial court refused to allow evidence of Skipper’s good adjustment to prison. Since that relevant mitigating evidence was excluded the Court reversed on Eddings grounds. Skipper, 476 U.S. at -, 106 S.Ct. at 1673.
The- most recent Supreme Court case to look at mitigating evidence was Hitchcock v. Dugger, — U.S. -, 107 S.Ct. 1821, 95 L.Ed.2d 347 (1987). In that case, the defendant Hitchcock introduced evidence of consequences of his childhood habit of inhaling gas fumes, together with other misfortunes of his youth. Hitchcock, 107 S.Ct. at 1823-24. The court of appeals affirmed the denial of habeas relief holding that the presentation of the evidence and Hitchcock’s attorney’s argument to “consider the whole picture, the whole ball of wax,” was sufficient to show that he had “an individualized sentencing hearing.” Hitchcock v. Wainwright, 770 F.2d 1514, 1518 (11th Cir.1985) (en banc), rev’d sub nom., Hitchcock v. Dugger, — U.S. -, 107 S.Ct. 1821, 95 L.Ed.2d 347 (1987). A unanimous Supreme Court reversed. Hitchcock, 107 S.Ct. at 1821. Instead of looking to what evidence was presented to the jury and the argument of defense counsel, the Court focused on the jury instructions and the prosecutor’s argument. Id. at 1823-24. The Florida statute at the time of trial provided for consideration of certain enumerated aggravating circumstances and certain enumerated mitigating circumstances. Id. at 1822-23. Although there was some doubt whether the Florida statute prohibited the use of nonstatutory mitigating circumstances, the court did not address the issue “[b]ecause our examination of the sentencing proceedings actually conducted in this case convinces us that the sentencing judge assumed such a prohibition and instructed the jury accordingly_” Id. at 1823. The Court focused on both the prosecutor’s argument and the jury instructions. The prosecutor told the jury “to consider the mitigating circumstances and consider those by number,” and he went down the list item by item. Id. at 1824. The trial judge instructed the jury that “[t]he mitigating circumstances which you may consider shall be the following” and then listed the statutory mitigating circumstances. Id. at 1824. The Court concluded: “[w]e think it could not be clearer that the advisory jury was instructed not to consider, and the sentencing judge refused to consider, evidence of non-statutory mitigating circumstances, and that the proceedings therefore did not comport with the requirements of Skipper v. South Carolina, Eddings v. Oklahoma, and Lockett v. Ohio.” Id. (citations omitted).
It is therefore abundantly clear that a sentencing authority must not be precluded from considering any, or almost any, mitigating evidence. The issue here is what the term “consider” means. The Supreme Court has held that presentation of mitigating circumstances to the sentencing authority is not enough: “[n]ot only did the Eighth Amendment require that capital-sentencing schemes permit the defendant *924to present any relevant mitigating evidence, but ‘Lockett requires the sentencer to listen’ to that evidence.” Sumner v. Shuman, — U.S. -, -, 107 S.Ct. 2716, 2722, 97 L.Ed.2d 56 (1987) (quoting Eddings, 455 U.S. at 115, n. 10, 102 S.Ct. at 877, n. 10). We read the Court’s command that the sentencer not be precluded from “considering” any mitigating circumstances to mean that the sentencer not be precluded from listening to and acting upon any mitigating circumstance. That is not to say that the aggravating and mitigating circumstances must be balanced in any particular way. See Zant v. Stephens, 462 U.S. 862, 873-80, 103 S.Ct. 2733, 2741-44, 77 L.Ed.2d 235 (1983). It is simply to say that the jury may not be precluded from allowing the evidence of mitigation to enter into their decision.
The Supreme Court, in effect, has approached capital cases from two different ends. First, “a State must ‘narrow the class of murderers subject to capital punishment,’ by providing ‘specific and detailed guidance’ to the sentencer.” McCleskey v. Kemp, — U.S. -, -, 107 S.Ct. 1756, 1772-73, 95 L.Ed.2d 262 (1987) (citations omitted) (citing Gregg, 428 U.S. at 196, 96 S.Ct. at 2936 and Proffitt, 428 U.S. at 253, 96 S.Ct. at 2967). On the other side, “the Constitution limits a State’s ability to narrow a sentencer’s discretion to consider relevant evidence that might cause it to decline to impose the death sentence.” McCleskey, 107 S.Ct. at 1773; see also Shuman, 107 S.Ct. at 2723 (Eighth Amendment violated by statute that requires the death sentence for defendant who murders while serving a life sentence without the possibility of parole); see generally California v. Brown, — U.S. -, -, 107 S.Ct. 837, 841-42, 93 L.Ed.2d 934 (1987) (O’Connor, J., concurring) (discussing the “tension” between “the two central principles of our Eighth Amendment jurisprudence”).
Turning back to the Texas sentencing procedure, we see that the jury is to respond to three “special issues.” The third issue involves provocation by the deceased. Tex.Crim.Proc.Code Ann. art. 37.071(b). It rarely enters into the decision of the jury. Instead, the focus is on the first two questions: whether the killing was deliberate with the reasonable expectation that death would follow and whether “there is a probability that the defendant would commit criminal acts of violence that would constitute a continuing threat to society.” Tex.Crim.Proc.Code Ann. art. 37.071(b). The Texas Court of Criminal Appeals has consistently held that the words of these special issues have clear meanings that need no definition. Penry, 691 S.W.2d at 653-54. The jury is instructed, as here, that in answering “each Special Issue you may take into consideration all of the evidence .... ” No jury instruction on mitigating evidence is necessary because “[t]he jury can readily grasp the logical relevance of mitigating evidence to the issue of whether there is a probability of future criminal acts of violence.” Cordova v. State, 733 S.W.2d 175, 190 (Tex.Crim.App.1987) (quoting Quinones v. State, 592 S.W.2d 933, 947 (Tex.Crim.App.), cert. denied, 449 U.S. 893, 101 S.Ct. 256, 66 L.Ed.2d 121 (1980)).
The issue, then, is whether the questions, within their common meaning, permit the jury to act on all of the mitigating evidence in any manner they choose. In other words, is the jury precluded from the individual sentencing consideration that the Constitution mandates? The jury may only find whether the murder was deliberate with a reasonable expectation of death and whether there is a probability that the defendant will in the future commit criminal acts of violence that constitute a threat to society. Although most mitigating evidence might be relevant in answering these questions, some arguably mitigating evidence would not necessarily be. The jury, then, would be effectively precluded from acting on the latter. Actually, these questions are directed at additional aggravating circumstances. Once found beyond a reasonable doubt, the death penalty is then mandatory.5 The jury cannot say, based *925on mitigating circumstances, that a sentence less than death is appropriate. How can a jury act on its “discretion to consider relevant evidence that might cause it to decline to impose the death penalty”? McCleskey, 107 S.Ct. at 1773. Where, in the Texas scheme is the “moral inquiry” of the “individualized assessment of the appropriateness of the death penalty”? Brown, 107 S.Ct. at 841 (O’Connor, J., concurring).
We recognize that Jurek specifically upheld the Texas statute, as the state argues. Developing Supreme Court law, however, recognizes a constitutional right that the jury have some discretion to decline to impose the death penalty. There is a question whether the Texas scheme permits the full range of discretion which the Supreme Court may require.6 Perhaps, it is time to reconsider Jurek in light of that developing law.7
Penry’s conviction is a good example of mitigating circumstances that pose a problem under the Texas scheme. Penry introduced evidence of his mental retardation and his inability to read or write. He had never finished the first grade. His emotional development was that of a child. He had been beaten as a child, locked in his room without access to a toilet for considerable lengths of time. He had been in and out of a number of state schools. One effect of his retardation was his inability to learn from his mistakes.
The evidence is similar to that in Hitchcock and Eddings. Those cases arguably teach us that it must be considered by the sentencer. Yet the Penry jury was allowed only to answer two questions. First, was the killing deliberate with reasonable expectation of death. Having just found Pen-ry guilty of an intentional killing, and rejecting his insanity defense, the answer to that issue was likely to be yes. Although some of Penry’s mitigating evidence of mental retardation might come into play in considering deliberateness, a major thrust of the evidence on his background and child abuse, logically, does not. The second question then asked whether Penry would be a continuing threat to society. The mitigating evidence shows that Penry could not learn from his mistakes. That suggests an affirmative answer to the second question. What was the jury to do if it decided that Penry, because of retardation, arrested emotional development and a troubled youth,8 should not be executed? If anything, the evidence made it more likely, not less likely, that the jury would answer the second question yes. It did not allow the jury to consider a major thrust of Penry’s evidence as mitigating evidence. We do not see how the evidence of Penry’s arrested emotional development and troubled youth could, under the instructions and the special issues, be fully acted upon by the jury. There is no place for the jury to say “no” to the death penalty based on a principal mitigating force of those circumstances.
The state argues that Penry’s counsel could, and did, argue the mitigating circumstances to the jury. The defense attorney in Hitchcock also argued to the jury to “consider the whole picture, the whole ball of wax.” 107 S.Ct. at 1824. The prosecu*926tor in Hitchcock then stood up and argued to the jury to consider the mitigating circumstances by number. Id. Likewise, here, the prosecutor was able to trump the defense counsel’s argument:
I didn’t hear Mr. Newman or Mr. Wright [defense attorneys] say anything to you about what your responsibilities are. In answering these questions based on the evidence and following the law, and that's all that I asked you to do, is go out and look at the evidence. The burden of proof is on the State as it has been from the beginning, and we accept that burden. And I honestly believe that we have more than met that burden, and that’s the reason you didn’t hear Mr. Newman argue. He didn’t pick out these issues and point out to you where the State had failed to meet this burden. He didn’t point out the weaknesses in the state’s case because, ladies and gentlemen, I submit to you we’ve met our burden.
As in Hitchcock, the mere fact that defense counsel argued mitigating circumstances does not conclude the matter. The question is whether the jury could act on the mitigating circumstances and not impose the death penalty. The prosecutor’s argument would exclude that consideration.

Jurek expressly held that the Texas statute is constitutional. After Jurek, the Court has reiterated that stance a number of times. For example, in Lockett the Court stated that the Texas statute “survived the petitioner’s Eighth and Fourteenth Amendment attack because three Justices concluded that the Texas Court of Criminal Appeals had broadly interpreted the second question — despite its facial narrowness — so as to permit the sentencer to consider ‘whatever mitigating circumstances’ the defendant might be able to show.” Lockett, 438 U.S. at 607, 98 S.Ct. at 2966. Similar reasoning has been used in a number of other cases. See, e.g., Zant, 462 U.S. at 875 n. 13, 103 S.Ct. at 2742 n. 13; Lockhart v. McCree, 476 U.S. 162, -, 106 S.Ct. 1758, 1769-70, 90 L.Ed.2d 137 (1986). We think that a strong argument can be made that developing law, see, e.g., Hitchcock, is inconsistent. However, even if we were free to decide that inconsistency and reach a different result, see Brock v. McCotter, 781 F.2d 1152, 1157 n. 5 (5th Cir.), cert. denied, — U.S. -, 106 S.Ct. 2259, 90 L.Ed.2d 704 (1986), we are not free to do so because prior Fifth Circuit decisions have rejected claims similar to Penry’s. Riles v. McCotter, 799 F.2d 947, 952-53 (5th Cir.1986); Granviel v. Estelle, 655 F.2d 673, 675-77 (5th Cir.1981), cert. denied, 455 U.S. 1003, 102 S.Ct. 1636, 71 L.Ed.2d 870 (1982). These prior panel holdings bar a different holding by us,

The stay of execution is vacated. The judgment denying the writ is AFFIRMED.
. At the time of Penry’s offense, section 19.03 of the Texas Penal Code Ann. (Vernon 1974) provided:
(a) A person commits an offense [of capital murder] if he commits murder as defined under Section 19.02(a)(1) of this code and:
(1) the person murders a peace officer or fireman who is acting in the lawful discharge of an official duty and who the person knows is a peace officer or fireman;
(2) the person intentionally commits the murder in the course of committing or attempting to commit kidnapping, burglary, robbery, aggravated rape, or arson;
(3) the person commits the murder for remuneration or the promise of remuneration or employs another to commit the murder for remuneration or the promise of remuneration;
(4) the person commits the murder while escaping or attempting to escape from a penal institution; or
(5) the person, while incarcerated in a penal institution, murders another who is employed in the operation of the penal institution.
Penry was found guilty of a violation of subsection (a)(2), "in the course of committing and attempting to commit the offense of aggravated rape.” Penry v. State, 691 S.W.2d at 641.
Subsequent amendments have changed "aggravated rape” to “aggravated sexual assault” and have added:
(6)the person murders more than one person:
(A) during the same criminal transaction; or
(B) during different criminal transactions but the murders are committed pursuant to the same scheme or course of conduct.

. Furman v. Georgia, 408 U.S. 238, 92 S.Ct. 2726, 33 L.Ed.2d 346 (1972). Furman effectively struck down all capital punishment statutes in place at that time.
. Only three members of the Court, Justices Stewart, Powell and Stevens, were in the majority in Gregg as well as the four other death penalty cases decided that day. Jurek v. Texas, 428 U.S. 262, 96 S.Ct. 2950, 49 L.Ed.2d 929 (1976); Proffitt v. Florida, 428 U.S. 242, 96 S.Ct. *9212960, 49 L.Ed.2d 913 (1976); Woodson v. North Carolina, 428 U.S. 280, 96 S.Ct. 2978, 49 L.Ed.2d 944 (1976); Roberts v. Louisiana, 428 U.S. 325, 96 S.Ct. 3001, 49 L.Ed.2d 974 (1976). Those opinions, as confirmed by subsequent decisions, represent the law involved.
. The sentencer may be a judge instead of a jury. See discussion concerning Proffitt, infra p. 921.
. Commentators have expressed similar views. See Benson, Texas Capital Sentencing Procedure *925After Eddings: Some Questions Regarding Constitutional Validity, 23 S.Tex.L.J. 315 (1982); Green, Capital Punishment, Psychiatric Experts, and Predictions of Dangerousness, 13 Capital U.L.Rev. 533 (1984). Green argues that once the prosecutor’s psychiatrist pronounces a defendant a sociopath, as usually happens, the answer to the future dangerousness issue is preordained. Id. at 553.
.Justice White, concurring in part, dissenting in part and concurring in the judgment in Lockett states, "[i]t... seems to me that the plurality strains very hard and unsuccessfully to avoid eviscerating the handiwork in Proffitt v. Florida and Jurek v. Texas...." Lockett, 438 U.S. at 623, 98 S.Ct. at 2983 (citations omitted). It was the same Florida statute that was approved in Proffitt that was applied unconstitutionally in Hitchcock.
. The United States Supreme Court has recently granted certiorari in Franklin v. Lynaugh, 823 F.2d 98 (5th Cir.1987), cert. granted, 56 U.S.L.W. 3287 (U.S. Oct. 9, 1987) (No. 87-5546), limited to the question:
Whether the jury must be instructed on the effect of mitigating evidence under the Texas capital punishment scheme.
. Penry, apparently, was approximately 22 years old at the time of the crime.
