Defendant, John Samuel Jolley, appeals from judgment of conviction of first-degree murder claiming, inter alia, that the trial court’s instructions to the jury on the defense of mental illness were inadequate. We affirm.
Defendant was an employee of a discount store in Northeast Minneapolis. On the afternoon of August 31, 1991, while working at the store, he spotted the victim, 8-year-old Margaret Marques, who had gone to the basement of the store to use the bathroom. Defendant, having long fantasized about kidnapping a woman or a girl, put his hand over the victim’s mouth, unsuccessfully attempted to knock her out with a rubber mallet, then *771carried her to a boiler room where he strangled her until she lost consciousness. He then placed her in a box and carried her out to his car. After telling a fellow employee that he was ill, he drove the victim to the house of his parents (his mother and stepfather), where he also lived. Knowing that his parents would not be home for some time, defendant undressed the victim, showered with her, and sexually assaulted her. He then put her back in the box and carried her to the basement. He stayed in the basement with her after his parents returned home. They apparently were unaware of the presence of the victim in the house.
The following day, after his parents left, defendant took the victim to the apartment of his brother, who was not home. That night, when the victim got up to use the bathroom, defendant put her in the bath tub and drowned her. After sexually assaulting her again, he removed her body from the apartment, disposed of her clothing in a dumpster near the apartment and disposed of the body in Lakeville in a wooded area near Highway I-35W.
Defendant subsequently confessed to the police and was thereafter charged by indictment with three counts of first-degree murder. Found competent to stand trial, defendant pleaded guilty to the elements of the offenses but demanded a jury trial on the issue of the defense of mental illness.
At the trial defendant claimed to be suffering from “multiple personality disorder,” maintaining that an alter personality, “Jack,” which resulted from being physically abused as a child by his father, controlled his actions and in fact committed the crimes.
Dr. Carl Malmquist, the court-appointed expert, was called by the defense. He diagnosed defendant as indeed having a “multiple personality disorder,” a diagnosis he based on information received from defendant and on the manner in which defendant related the events. He testified that he believed defendant knew the nature of his act and that it was wrong when he did it. He testified that defendant’s behavior “raised questions” with respect to volition but that he did not see that volition was part of the legal question being asked. Asked by the prosecutor on cross-examination, “[I]s it your understanding of the insanity defense in Minnesota that it is cognition that is relevant and not volition,” he was allowed to answer, over objection, “That’s my understanding.” Asked basically the same question on recross-examination, Dr. Malmquist said he would leave to the lawyers whether volition was relevant to the defense but that it was his understanding that it was not.
Dr. R. Owen Nelson, also testifying for the defense, agreed with Dr. Malmquist’s diagnosis and with his opinion that defendant knew the nature of his act and that it was wrong when he committed the act. Asked whether in his opinion defendant was in volitional control at the time of his conduct, he said that he did not have an opinion “regarding anything that relates to the legal aspect of it * * *"
Dr. William Percy, a psychologist specializing in “multiple personality disorder,” testified for the state that, based on his review of the record, he did not believe defendant was suffering from the disorder. Agreeing with the others, he testified that defendant knew the nature of his act and that it was wrong at the time he committed it. With respect to volition, he testified that it was “very clear” that defendant was “in executive control” when he committed the act.
In closing arguments, the prosecutor argued that cognition was relevant but not volition. Defense counsel did not object or ask for a curative instruction.
Defense counsel did submit proposed jury instructions on the defense of mental illness. Those instructions included CRIM-JIG 6.02,1 the standard recommended jury *772instruction, with the following language added:
To decide whether defendant knew the nature of his act or to decide whether defendant understood that the act was wrong, you may give credence to all the evidence introduced that relates to cognition, volition, and capacity to control behavior.
The trial court refused to give the requested additional language.
CRIMJIG 6.02, which the trial court submitted, states the test for mental illness set forth in Minn.Stat. § 611.026, which is a codification of the so-called M’Naghten Rule in Minnesota. The M’Naghten Rule has been upheld by the United States Supreme Court against a due process claim. Leland v. Oregon, 343 U.S. 790, 72 S.Ct. 1002, 96 L.Ed. 1302 (1952).
Defendant argues, however, that the proposed addition to CRIMJIG 6.02 is consistent with state law, pointing out that the language in question is taken from this court’s holding in State v. Rawland, 294 Minn. 17, 199 N.W.2d 774 (1972). In Rawland this court summarized its holding as follows:
In determining whether or not a defendant has met the burden imposed on him by statute to prove absence of guilt because of insanity, the factfinder may give credence to competent evidence that relates to cognition, volition, and capacity to control behavior. The basic question of fact remains, however, whether in the light of this burden and this evidence the defendant was laboring under such a defect of reason as not to know “the nature of his act, or that it was wrong.”
294 Minn, at 46, 199 N.W.2d at 790.
As the state points out, however, Rawland did not address or decide the question whether instructions regarding volition or capacity to control behavior are required. Moreover, in State v. Larson, 281 N.W.2d 481, 486 including at n. 4 (Minn.), cert, denied, 444 U.S. 973,100 S.Ct. 467, 62 L.Ed.2d 388 (1979), this court not only recommended using CRIMJIG 6.02, the instruction used here, but also stated, “We hold that an instruction on capacity to control behavior need not be given.” Subsequently, in State v. Carlson, 328 N.W.2d 690, 694-95 (Minn. 1982), and in State v. LaTourelle, 343 N.W.2d 277, 283 (Minn.1984), we reaffirmed what we said in Larson.
The fact that the language proposed by defendant is taken from our decision in Raw-land does not mean that the trial court was obligated to use the language in the instructions. As we have indicated on other occasions, a trial court is not obligated to give a proposed instruction simply because the instruction contains language taken from a decision of this court. See, e.g., State v. Turnipseed, 297 N.W.2d 308, 312 (Minn.1980) (not every sufficiency of the evidence test articulated by the supreme court should be read to the jury by the trial court in instructions).
Further, as we said recently in State v. Olson, 482 N.W.2d 212, 216 (Minn.1992), “as a general matter” it is the “wiser course” for trial courts to “avoid as much as possible the giving of instructions on particular kinds of evidence.”
In conclusion, we reject the contention that trial courts, when requested, are obliged to include the language from Rawland concerning volition when instructing the jury on the M’Naghten Rule.
We are troubled, however, by the prosecutor’s statement in closing argument that the jury was not free to consider evi-*773denee as to volition in determining whether defendant met his burden of proof under M’Naghten. This statement was a misstatement of law. Any time a prosecutor makes such a misstatement of law, the defense is free to object and ask for a curative instruction.
Here if defense counsel had objected expressly to the prosecutor’s statement and phrased the request for an instruction as a request for a curative instruction, the trial court may well have agreed to give the instruction requested or something else along the lines of the requested instruction. While we have no difficulty concluding that the trial court should have given a curative instruction correcting the prosecutor’s misstatement, we disagree with any suggestion that the trial court’s failure to give such an instruction constituted prejudicial error. As our brief summary of the evidence demonstrates, the evidence that defendant was mentally ill at the time he committed the act was very weak, and it is extremely unlikely that the giving of a curative instruction would have changed the result. Under the circumstances, we have no hesitancy in concluding that defendant is not entitled to a new trial on this ground.
Having carefully considered this contention and the other contentions raised by defendant, we affirm.
Affirmed.
WAHL, J., dissents in part and concurs in part and files opinion.. CRIMJIG 6.02 provides:
Under the statutes of Minnesota, a person is not criminally liable for an act when, at the time of committing the act, the person did not know the nature of the act, or did not know that it was wrong because of a defect of reason caused by a mental illness or deficiency. The defense of [mental illness or mental deficiency] is as follows:
First, defendant did not know the nature of the act. This means, defendant did not understand what the defendant was doing. If be*772cause of a defect of reason, defendant did not know what action the defendant was taking or what the consequences of the defendant’s action would be, then defendant did not know the nature of the act.
Second, even if defendant knew the nature of the act, the defendant did not understand that the act was wrong. [The word "wrong” is used in the moral sense and does not simply refer to a violation of a statute. Stated another way, even if defendant realized that the act violated the law, defendant is not criminally liable if, because of a defect of reason, defendant did not understand that the act was morally wrong.]
Third, the failure of the defendant to know the nature of the act or that it was wrong, must have been the result of a defect of reason caused by [mental illness] [mental deficiency].
