*921 OPINION
MEYERS, J.,delivered the opinion of the Court
in which KELLER, P.J., PRICE, WOMACK, KEASLER, HERVEY, HOLCOMB, and COCHRAN, JJ., joined.Appellant was convicted of capital murder in September 1999. Tex. Penal Code Ann. § 19.03(a). Pursuant to the jury’s answers to the special issues set forth in Texas Code of Criminal Procedure article 37.071, sections 2(b) and 2(e), the trial judge sentenced appellant to death. Art. 37.071 § 2(g).1 Direct appeal to this Court is automatic. Art. 37.071 § 2(h).
On December 15, 1998, at approximately 8:00 or 8:30 a.m., Esmerelda Lester and her 15-year old daughter Melanie Alma-guer went to Chris Lentsch’s home. Lentsch rented rooms to Travis Brown and Daniel Hibbard. Brown and appellant were in Brown’s room. While Lester, Al-maguer and Hibbard sat in Lentseh’s room, Lentsch went into the kitchen. Shortly thereafter, Lentsch heard gunshots from Brown’s room and turned to see appellant exiting the room with a gun in his hand. Appellant claimed that Brown had just shot himself. Lentsch told appellant to put the gun down, but appellant ordered Lentsch and the other three back into Lentsch’s room where he calmly walked up to Almaguer and shot her in the head, leaving her alive, but paralyzed from the neck down. Appellant then shot Hib-bard in the head, causing his death. Appellant finally pointed the gun at Lester, whereupon he discovered that he was out of bullets. Appellant thereafter rummaged through the house, set fire to Brown’s room, threatened Lester and Lentsch, and finally left in Brown’s car.
The police identified appellant as the killer and went to arrest him. Upon being arrested, appellant became violent. Officers discovered that appellant had told his father to lie for him and had persuaded his girlfriend to give him an alibi, which she maintained until confronted by the police. A fellow inmate testified that appellant showed no remorse for the shootings and stated that he wished he had killed them all.
Appellant took the stand and at first testified that although he had been to the house earlier, he was not there on the morning of the shootings. After defense counsel requested a recess, appellant took the stand and stated that he had lied in his previous testimony. He then testified that he was at the house at the time of shootings, and admitted that he had shot all three people and taken Brown’s car. Appellant claimed he shot Brown in self-defense after Brown had threatened to shoot him.2 He claimed that he shot the others because he panicked after shooting Brown.
During the punishment phase, the State put on evidence of appellant’s prior criminal history, including an aggravated robbery, various assaults and thefts, and a charge for resisting arrest. The State presented additional evidence that appellant had been repetitively belligerent and disruptive at school and that he had gotten into a fight with jailers while incarcerated.
In his tenth point of error, appellant claims that the evidence presented at trial was legally insufficient to support the *922jury’s finding that he would be a continuing threat to society. See Art. 37.071 § 2(b)(1). In reviewing the sufficiency of the evidence at punishment, this Court looks at the evidence in the light most favorable to the verdict to determine whether any rational trier of fact could have believed beyond a reasonable doubt that appellant would probably commit criminal acts of violence that would constitute a continuing threat to society. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979); Allridge v. State, 850 S.W.2d 471 (Tex.Crim.App. 1991), cert, denied, 510 U.S. 831, 114 S.Ct. 101, 126 L.Ed.2d 68 (1993). The facts of the crime alone can be sufficient to support the affirmative finding to the special issue. Allridge, 850 S.W.2d at 488. Additionally, we have consistently defined “society” as encompassing both the prison population and the free population. See Griffith v. State, 983 S.W.2d 282, 300 n. 9 (Tex.Crim.App.), cert. denied, 528 U.S. 826, 120 S.Ct. 77, 145 L.Ed.2d 65 (1999).
The facts in the instant case demonstrate a calculated crime which culminated in execution-style killings. The State’s evidence reflected that appellant was always in control of his actions and showed no remorse. In addition to these facts, the State showed that appellant had a litany of past behavior problems and had committed a number of criminal violations. Given the facts in the instant case, and the nature and number of the other extraneous acts shown, a rational jury could reasonably have concluded that appellant would continue to be a threat to society. The evidence is legally sufficient to support the jury’s affirmative answer to the future dangerousness issue. Jackson and All-ridge, both supra. Point of error ten is overruled.
In his first two points of error, appellant claims the trial court erred in denying his challenges for cause to two venirepersons. To preserve error on allegedly erroneously denied challenges for cause, an appellant must demonstrate that he asserted a clear and specific challenge for cause, that he used a peremptory challenge on the complained-of venireperson, that all of his peremptory challenges were exhausted, that his request for additional strikes was denied, and that an objectionable juror sat on the jury. Green v. State, 934 S.W.2d 92, 105 (Tex.Crim.App.1996), cert. denied, 520 U.S. 1200, 117 S.Ct. 1561, 137 L.Ed.2d 707 (1997). The record in the instant case shows that appellant used only thirteen of his fifteen peremptory challenges. Appellant has failed to preserve error on these points. Points of error one and two are overruled.
In his third point of error, appellant claims the trial court erred in granting the State’s challenge for cause to veni-reperson Villamayor based on her views against the death penalty. Under Wainwright v. Witt, 469 U.S. 412, 105 S.Ct. 844, 83 L.Ed.2d 841 (1985), a venireperson may be excluded for cause consistent with the Sixth Amendment to the United States Constitution when his views on capital punishment are such that they would “prevent or substantially impair the performance of his duties as a juror in accordance with his instructions and his oath.” Clark v. State, 929 S.W.2d 5, 6-7 (Tex. Crim.App.1996), cert, denied, 520 U.S. 1116, 117 S.Ct. 1246, 137 L.Ed.2d 328 (1997); Vuong v. State, 830 S.W.2d 929, 942 (Tex.Crim.App.), cert. denied, 506 U.S. 997, 113 S.Ct. 595, 121 L.Ed.2d 533 (1992); Moody v. State, 827 S.W.2d 875, 888 (Tex. Crim.App.), cert. denied, 506 U.S. 839, 113 S.Ct. 119,121 L.Ed.2d 75 (1992). Prospective jurors may not be excused merely because their beliefs about the death penalty might influence the decision-making process. Clark, supra.
*923Two weeks prior to Villamayor’s individual questioning, the trial judge explained to the entire panel of veniremembers the procedural sequence of a death penalty case. The judge told the panel that the jury is first called upon to decide whether a capital murder defendant is guilty. The judge continued to explain that, if the jury found the defendant to be guilty, then the trial continued into a second phase where punishment was determined. The judge stressed to the veniremembers that a Texas jury is never required to assess a sentence of death or life imprisonment. Rather, the jury is required to answer a series of questions, and the answers to those questions would dictate to the judge what punishment should be assessed. Finally, the judge described to the panel the questions the jury would be required to answer.
During Villamayor’s individual questioning, the prosecutor first went through several answers she had given on her questionnaire indicating that she was morally opposed to the death penalty. The prosecutor also noted responses in which Villa-mayor had indicated that she believed that there were circumstances in which the death penalty was appropriate. However, in response to specific questioning, Villa-mayor commented that killing just two individuals was not such a case. Rather, Villamayor stated that she felt the death penalty was appropriate only in such cases as when a person “kill[ed] a whole village.”
The prosecutor then reminded Vil-lamayor of the judge’s instructions and explanations two weeks earlier and proceeded to expand upon the procedure followed in the punishment phase of a capital trial, the meanings of the questions asked, and the law involved.3 As the prosecutor explained the mitigation question and asked the venireperson questions concerning it, the fohowing exchange occurred:
[PROSECUTOR:] [A]re you of such a nature, ma’am, that you wül almost always answer this [mitigation question] yes because then you know the person probably would receive a Life Sentence? Are you in that category, or would you go ahead and look at it and then answer it appropriately?
[[Image here]]
MS. VILLAMAYOR: I would probably be in that category.
[PROSECUTOR:] That you would auto-maticaEy answer it?
MS. VILLAMAYOR: Yes, I think I would.
[PROSECUTOR:] Are your—are your feelings about the Death Penalty, is that the reason why you would probably au-tomaticaUy always find mitigating circumstances?
MS. VILLAMAYOR: Yes.
[[Image here]]
[PROSECUTOR:]—are your behefs so strong, ..., you are going to have problems setting them aside?
MS. VILLAMAYOR: I beheve they are.
[PROSECUTOR:] Do you think—let me ask you one last time in regard to—and in a different fashion so that we are clear and there is no conflict here. Do you—do you beheve that your personal opinions, your personal beliefs about the Death Penalty, being opposed to it, is going to substantially affect you in answering this question regarding mitigating circumstances?
*924MS. VILLAMAYOR: Yes.
The prosecutor then challenged Villamayor for cause and the judge passed her to the defense for questioning. During defense counsel’s questioning, Villamayor continued to state that her beliefs would influence her judgment and she was not sure that she could be open-minded during the process.
Given the totality of the voir dire, the trial judge was within his discretion in determining that Villamayor’s views on capital punishment were such that they would have prevented or substantially impaired the performance of her duties as a juror in accordance with her instructions and her oath. Wainwright, supra; see also Colburn v. State, 966 S.W.2d 511, 518 (Tex.Crim.App.1998). Point of error three is overruled.
Appellant asserts in his fourth and fifth points of error that the trial court erred in overruling his Batson challenge to the State’s use of peremptory strikes on prospective jurors J. Grooms and M. Adams.4 See Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986). Under Batson, a defendant must initially establish a prima facie showing of racial discrimination in the State’s exercise of its peremptory strikes. The burden then shifts to the State to articulate race-neutral explanations for its questioned strikes. Once the prosecutor has articulated race-neutral explanations, the burden shifts back to the defendant to show that the explanations are really a pretext for discrimination.5 The trial court must then determine whether the defendant has carried his burden of proving racial discrimination. The trial court’s determination is accorded great deference and will not be overturned on appeal unless it is clearly erroneous. See Chamberlain v. State, 998 S.W.2d 230, 236 (Tex.Crim.App.1999), cert. denied, 528 U.S. 1082, 120 S.Ct. 805, 145 L.Ed.2d 678 (2000).
During the Batson hearing in the instant case, the prosecutor explained that he had struck venireperson Grooms because she had indicated that she was in favor of the death penalty only in those instances where the defendant requested the death penalty and the crime was of the most violent nature. She also noted that she felt the death penalty was imposed too often and that Texas had put a lot of people to death. With regard to prospective juror Adams, the prosecutor told the judge that he had struck her because she had indicated that she needed proof beyond any doubt and because she had two children, one of whom was about appellant’s age.
The trial court then gave appellant an • opportunity to rebut the prosecutor’s explanations. Appellant responded by stating that the prosecutor used his strikes in a improper manner and that this was the most blatant violation of due process he had seen in twenty-three years of practicing law. The trial court overruled the Batson claim.
The State’s explanations were facially race-neutral and appellant did not point to any evidence of pretext. The trial court did not abuse its discretion in finding that appellant failed to carry his burden of *925showing purposeful discrimination. See Pondexter, v. State, 942 S.W.2d 577, 581-82 (Tex.Crim.App.1996)(defendant’s rebuttal insufficient to establish State’s explanations were pretext); Chambers v. State, 866 S.W.2d 9, 25 (Tex.Crim.App.l993)(“absent some other evidence which rebuts the State’s race-neutral explanation, we will not disturb the trial court’s finding that the State’s explanation is legitimate”). Appellant’s fourth and fifth points of error are overruled.
In his sixth point of error, appellant claims the trial court erred in refusing to instruct the jury on the lesser-included offense of manslaughter in the death of Daniel Hibbard, the second victim named in the indictment. He asserts that a finding that he was guilty of a lesser degree of criminal homicide in Hibbard’s case would necessarily negate one of the elements required to convict him of capital mui'der. He contends that the evidence raising the issue of whether he was guilty of the lesser degree of criminal homicide came from his own testimony. Specifically, appellant repeatedly denied during his testimony that he had intended to kill anyone. He claimed that he killed Brown in self-defense and then just pulled the trigger in a panic when Hibbard turned around, but insisted he was acting recklessly and not intentionally.
To determine whether a charge on a lesser-included offense should be given, this Court has implemented a two-step test. See Aguilar v. State, 682 S.W.2d 556, 558 (Tex.Crim.App.1985); Royster v. State, 622 S.W.2d 442, 444 (Tex.Crim.App.1981) (plurality opinion). The first step is to decide whether the offense is a lesser-included offense of the offense charged. See Article 37.09; see also, e.g., Rousseau v. State, 855 S.W.2d 666, 672 (Tex.Crim. App.), cert. denied, 510 U.S. 919, 114 S.Ct. 313, 126 L.Ed.2d 260 (1993); Aguilar, 682 S.W.2d at 558. We have recognized that manslaughter is a lesser-included offense of capital murder. See Cardenas v. State, 30 S.W.3d 384, 392-93 (Tex.Crim.App. 2000). Hence, the first prong of the test is satisfied.
The second step of the Aguilar/Rousseau test requires an evaluation of the evidence to determine whether there is some evidence that would permit a jury rationally to find that the defendant is guilty only of the lesser offense. Moore v. State, 969 S.W.2d 4, 8 (Tex.Crim.App.1998); Rousseau, 855 S.W.2d at 672. In other words, there must be some evidence from which a jury could rationally acquit the defendant of the greater offense while convicting him of the lesser-included offense. Moore, 969 S.W.2d at 8. The evidence must establish the lesser-included offense as a valid rational alternative to the charged offense. Wesbrook v. State, 29 S.W.3d 103, 113-14 (Tex.Crim.App. 2000), cert. denied, 532 U.S. 944, 121 S.Ct. 1407, 149 L.Ed.2d 349 (2001); Arevalo v. State, 943 S.W.2d 887, 889 (Tex.Crim.App.1997).
Contrary to appellant’s claim that he shot Brown in self-defense, the medical examiner testified that Brown had suffered two bullet wounds to the head, one of which entered from the back. The evidence of appellant’s actions following Brown’s shooting reflected that he was calm and calculated, not that he was panicked or frightened. He shot Almaguer between the eyes and Hibbard in the head. Although appellant claimed he acted “recklessly” with the gun and did not intend to kill anyone, his testimony about the shootings was fraught with inconsistencies. For example, he vacillated between insisting he had not aimed the gun when shooting and stating that he had indeed aimed and shot:
*926I did not actually know at the time that I was — I was shooting [Almaguer], I did aim the gun and pull the trigger, but I never meaned [sic] — I just shot. I never aimed it or anything. It just hit her.... I never said I didn’t aim the gun and pull the trigger. I have been telling you the whole time that I did aim the gun and pull the trigger .... after they started hollering and screaming, then I went in there and that’s when I aimed and pulled the gun and pulled the trigger.... I said I pointed the gun — I said I pointed it — I aimed — I didn’t mean to just point it.... I just pointed it and shot.... I just pointed the gun and shot. I wasn’t even really just looking ... when I shot the gun, but I did aim it over there. I wasn’t never even looking ... I just pulled the trigger.... I just closed my eyes and shoot [sic].
Appellant’s testimony that he did not intend to kill anyone does not amount to evidence upon which a jury could rationally find appellant only acted recklessly with respect to killing Hibbard, and not intentionally. Appellant had already shot and killed Brown with two shots to the head. He admitted to aiming and firing the gun. With four shots, he killed two people and hit the third between her eyes. Those who saw him testified his actions were calm and collected. In a similar case, Wesbrook v. State, 29 S.W.3d 103 (Tex. Crim.App.2000), the defendant killed five people. He sought an instruction on a lesser-included offense of aggravated assault. We upheld the trial court’s refusal of the instruction:
The evidence must establish the lesser-included offense as a valid alternative to the charged offense. In the instant case, the trial record shows appellant acted intentionally, or at the least, knowingly, when he walked into an apartment armed with a high-powered rifle. He fired a single shot at close range into the chest of the first victim, a highly vulnerable part of the body. After untnessing the damage that resulted from his actions, appellant continued to fire the weapon, again at close range, into four more individuals, choosing as his target, either their head, chest, or abdomen. Physical evidence from the scene and the condition of the bodies suggest that one victim was shot as he attempted to escape from the apartment and another was shot while on his knees. The only contrary evidence that this was not an intentional or knowing act is appellant’s own assertion that he did not intend to kill. Given the state of the entire record, this was not evidence from which a jury could rationally conclude that appellant was guilty only of aggravated assault.
Wesbrook, 29 S.W.3d at 113-14 (emphasis added); see also Jackson v. State, 992 S.W.2d 469, 475 (Tex.Crim.App.1999) (not entitled to instruction on the lesser-included offense of aggravated assault when evidence showed appellant, at least, guilty of homicide). Apart from appellant’s own testimony that he did not intend to kill anyone, there was no other evidence in support of such theory, and in fact the evidence refuted that testimony. We hold appellant’s testimony does not supply evidence upon which a jury could rationally find appellant’s actions toward Hibbard were merely reckless and were not at least knowing. Hence, appellant has failed to satisfy the second prong of the Aguilar/Rousseautest. Appellant’s sixth point of error is overruled.
In his seventh point of error, appellant complains that “[t]he prosecutor committed reversible error when he referred to [a]ppellant in final argument as a ‘despicable piece of human trash.’” Appellant failed to object at trial to the prosecutor’s arguments, however, and therefore *927forfeited his right to complain about this issue on appeal. Tex.R.App. P. 33.1; Ladd v. State, 3 S.W.3d 547, 569 (Tex.Crim.App.1999), cert. denied, 529 U.S. 1070, 120 S.Ct. 1680, 146 L.Ed.2d 487 (2000). Appellant urges us to overrule Cockrell v. State, 933 5.W.2d 73 (Tex.Crim.App.1996), in which we held that a defendant must pursue to an adverse ruling his objections to jury argument. Appellant argues that such inflammatory, prejudicial statements cannot be cured by an instruction to disregard, and thus it would be pointless to object in order to secure an ineffective instruction. But even if an the error was such that it could not be cured by an instruction, appellant would be required to object and request a mistrial. Nonetheless, we decline to overrule Cockrell, a case perfectly in line with Rule of Appellate Procedure 33.1 and the policies underlying preservation of error. Point of error seven is overruled.
In his eighth point of error, appellant claims his trial counsel failed to render effective assistance by neglecting to object to the prosecutor’s comments during final argument concerning his non-testimonial courtroom demeanor.
To show an ineffective assistance of counsel claim, an appellant must first demonstrate that his trial counsel’s performance was deficient. Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984)(adopted by this Court in Hernandez v. State, 726 S.W.2d 53 (Tex.Crim.App.1986)). Second, he must also show that his counsel’s deficient performance was so serious that it prejudiced his defense, rendering the trial unfair and the verdict suspect. Strickland, 466 U.S. at 687, 104 S.Ct. 2052; Lockhart v. Fretwett, 506 U.S. 364, 113 S.Ct. 838, 122 L.Ed.2d 180 (1993). In other words, appellant must show by a preponderance of the evidence that trial counsel’s representation fell below an objective standard of reasonableness under prevailing professional norms and that this deficient performance rendered the result of the proceeding unreliable. Strickland, supra; McFarland v. State, 845 S.W.2d 824, 843 (Tex.Crim.App.1992), cert. denied, 508 U.S. 963, 113 S.Ct. 2937, 124 L.Ed.2d 686 (1993).
Appellant made no effort to prove the prejudice prong under Strickland. Ladd v. State, 3 S.W.3d 547, 570 (Tex.Crim.App.1999); Mitchell v. State, 989 S.W.2d 747, 748 (Tex.Crim.App.1999). Point of error eight is overruled.
In his ninth point of error, appellant claims the trial court erroneously overruled his objection to “victim impact” testimony concerning surviving victim Almaguer. Appellant relies on Cantu v. State, 939 S.W.2d 627 (Tex.Crim.App. 1997), cert. denied, 522 U.S. 994, 118 S.Ct. 557, 139 L.Ed.2d 399 (1997) as support for his claim.6
In Cantu, supra, the defendant was involved in the kidnaping, rape and murder of two girls in the same criminal episode. During the punishment phase of his trial for the kidnaping, rape and murder of one of the girls, the State presented testimony from the mother of the second victim regarding her daughter’s good character, the family’s search for her, and the impact of the crime on the family. The defendant objected that this “victim impact” evidence regarding a victim not named in the indictment was not relevant to the special issues, and that it was more prejudicial than probative. Id. at 636. We agreed that the *928evidence as to her good character, activities she enjoyed, and the impact of her death on her family was not relevant as appellant was not on trial for her murder and such evidence served no purpose other than to inflame the jury. We held such evidence to be irrelevant and highly prejudicial. Id. at 637.
The testimony at issue in the present case, however, is distinguishable from that evidence which was at issue in Cantu.
During the punishment phase of appellant’s trial, the State called Janelle Manning, a nurse who had been caring for Almaguer for approximately four months, to testify. Appellant objected, arguing that although the testimony of Manning was relevant, he felt that the prejudicial effect of the testimony far exceeded its probative value. The State, in response to appellant’s objection, argued that it would only be asking Manning to testify about the medical care provided to Almaguer on a daily basis and the things that were done in order to keep Almaguer alive. The trial court agreed to allow Manning to testify, however, it limited the testimony to the technical procedures required in the day-to-day care of Almaguer, while expressly curtailing any testimony regarding the psychological impact of Almaguer’s paralysis, or any testimony pertaining to her feelings of pain.
In Mosley v. State, 983 S.W.2d 249 (Tex. Crim.App.1998), cert. denied, 526 U.S. 1070, 119 S.Ct. 1466, 143 L.Ed.2d 550 (1999), we discussed the meaning of “victim impact” and “victim character” evidence. We explained that “victim impact” evidence is evidence that is “generally recognized as evidence concerning the effect that the victim’s death will have on others, particularly the victim’s family members.” Id. at 261. “Victim character” was defined as evidence that is “generally recognized as evidence concerning good qualities possessed by the victim.” Id.
The testimony at issue here does not fall under either category of victim-related evidence. Unlike in Cantu, in which the evidence involved testimony regarding both the victim’s good qualities and the effect that her death had on family members, the testimony in the present case did not involve testimony about how third persons were affected by the crime, nor was there any discussion about the character of the victim. Manning’s testimony focused solely on the medical procedures involved in the care of Almaguer. Appellant’s characterization of Manning’s testimony as victim impact evidence is incorrect. Point of error nine is overruled.
Appellant’s conviction is affirmed.

. Unless otherwise indicated all future references to Articles refer to the Code of Criminal Procedure.
. Appellant claimed Brown held the gun to appellant’s head and threatened to kill him. Appellant testified he knocked the gun out of Brown’s hand, and when Brown started walking toward him, appellant closed his eyes and pulled the trigger.
. Before a veniremember can be properly challenged for cause, the law must be explained to her and she must be asked whether she can follow that law regardless of her personal views. See Jones, 982 S.W.2d at 390.
. At trial appellant challenged nine of the State's strikes, but on appeal he complains only about the strikes to Grooms and Adams.
. Once the responding party has offered a race-neutral explanation for a peremptory challenge and the trial court has ruled on the ultimate question of purposeful discrimination, the preliminary issue of whether the party raising the Batson challenge made a prima facie case becomes moot. See Malone v. State, 919 S.W.2d 410, 412 (Tex.Crim.App.1996).
. Although appellant discusses Cantu, he does not actually develop an argument regarding the admission of the evidence.
