[1] Defendant’s first assignment oLerror relates to the alleged unconstitutionality of the judgment and sentence of death. Our Court has considered this on many occasions and found such argument to be without merit. State v. Young, 287 N.C. 377, 214 S.E. 2d 763 (1975); State v. Armstrong, 287 N.C. 60, 212 S.E. 2d 894 (1975); State v. Vick, 287 N.C. 37, 213 S.E. 2d 335 (1975); State v. Lowery, 286 N.C. 698, 213 S.E. 2d 255 (1975); State v. Simmons, 286 N.C. 681, 213 S.E. 2d 280 (1975); State v. Stegmann, 286 N.C. 638, 213 S.E. 2d 262 (1975); State v. Woods, 286 N.C. 612, 213 S.E. 2d 214 (1975); State v. McLaughlin, 286 N.C. 597, 213 S.E. 2d 238 (1975); State v. Avery, 286 N.C. 459, 212 S.E. 2d 142 (1975); State v. Williams, 286 N.C. 422, 212 S.E. 2d 113 (1975); State v. Jarrette, 284 N.C. 625, 202 S.E. 2d 721 (1974); State v. Waddell, 282 N.C. 431, 194 S.E. 2d 19 (1973). This assignment of error is overruled.
*442 [2] Next the defendant contends that the court erred in refusing to allow the defendant’s expert medical witness to state his definition of the word “intent.” The witness was a medical expert in the field of psychiatry. The defendant contends that in order for this witness to express his expert opinion it became necessary for him to be allowed to define the terms that would be used in his testimony. The defendant further contends that even though the judge instructed the jury about “intent,” this came long after the testimony of the expert and it was absolutely necessary for this witness to explain what he considered the word “intent” meant in order to relate this to his testimony.
It is the duty of the trial judge, not the psychiatrist, to explain the law and define legal terms such as “intent.” G.S. 1-180. “Intent” has a legal meaning somewhat different from a psychiatric definition, particularly the one proffered in this case out of the presence of the jury. As stated in State v. Bell, 285 N.C. 746, 750, 208 S.E. 2d 506, 508 (1974), “Intent is'a mental attitude seldom provable by direct evidence. It must ordinarily be proved by circumstances from which it may be inferred. [Citations omitted.]” The opinion of an expert witness is admissible in either of two situations: “(1) where the facts cannot adequately be presented to the jury, or (2) where the witness is better qualified than the jury to draw appropriate inferences from the facts.” 1 Stansbury, N. C. Evidence, § 132 (Brandis Rev. 1973). If the psychiatrist were permitted to give definitions to words that must later be given their legal definitions, this could confuse and possibly mislead the jury. It is within the trial court’s discretion to limit such potential confusion. In this case the psychiatrist was permitted to give his opinion of the mental condition of the defendant. It was not necessary that he give a psychiatrist’s definition of the term “intent” in order to express his opinion. The trial judge later properly defined “intent.” This assignment of error is without merit and is overruled.
[3] Next the defendant contends that the court committed prejudicial error in refusing to allow the expert psychiatrist to testify as to his opinion as to whether a person who was unable to conclude a complete thought or whose thoughts have no logical connection would be able to form successfully a specific plan or design to perform an act.
This assignment arose from a hypothetical question. The objection of the State was sustained. Counsel for defendant *443then composed a more complete hypothetical question relating specifically to defendant and the facts of this case and the witness was permitted to answer it. “It is customary to incorporate in a hypothetical question the relevant facts in evidence which counsel hopes will be accepted as true by the jury, and to ask the witness his opinion based on such facts if the jury shall believe them to be facts.” 1 Stansbury, N. C. Evidence, § 137 (Brandis Rev. 1973). The first hypothetical question was deficient because it did not relate specifically to defendant and the facts of this case and any answer might properly have been deemed ambiguous. Furthermore, since the opinion sought as to defendant under the facts of this case was the opinion expressed in the answer to a subsequent hypothetical question, there was absolutely no prejudice in refusing to allow the psychiatrist to answer the first question. This assignment of error is without merit and is overruled.
[4] Next the defendant contends it was error to allow the State’s expert psychiatrist to testify as a rebuttal witness and answer a purported hypothetical question calling for multiple opinions without the inclusion of the necessary facts within the question.
We have a different situation here from the hypothetical question posed to defendant’s witness. The State’s witness gave extensive testimony concerning his examination of the defendant. Following this he was asked if, based on that examination, hie had an opinion concerning defendant’s mental capacity. It is obvious from the record that the facts on which he based his opinion were clear. The question and the answer were proper under these circumstances. 1 Stansbury, N. C. Evidence, § 137 (Brandis Rev. 1973). This assignment is without merit and is overruled.
[5] Next, the defendant contends that the court committed prejudicial error in its charge to the jury when they were told that the defendant contended that he should be found “not guilty” of all charges.
The court charged the jury in the following language: “So he contends, Members of the Jury, that he should be acquitted of murder in the first degree and if convicted of anything, not more than murder in the second degree, but that he should in fact, so he contends, be found not guilty.”
*444In this connection the defendant asserts that this was error on the ground that his admission of the shooting amounted to an admission of second-degree murder and that the above statement by the trial judge was a misstatement of the defendant’s position. In effect, defendant is contending that the trial judge expressed an opinion in violation of G.S. 1-180.
In North Carolina when a defendant is charged with first-degree murder, he is not permitted to plead guilty to it. Certainly this does not work to the disadvantage of the defendant. The purpose of this rule is for the defendant’s protection and thereby requires the State to prove all the elements -of the offense beyond a reasonable doubt. It is true, as the defendant contends, that defendant’s own testimony shows elements of second-degree murder. This was noted by the trial judge, but it is also significant that defendant did not admit killing deceased. His plea of not guilty put into issue all of the elements of the charges against him and the burden remained on the State to satisfy the jury beyond a reasonable doubt of all of the elements of the offense charged, including the lesser offense of second-degree murder. See State v. Lewis, 274 N.C. 438, 164 S.E. 2d 177 (1968); State v. Ramey, 273 N.C. 325, 160 S.E. 2d 56 (1968). The proper placing of the burden on the State as the law requires was an advantage to the defendant. Certainly it was not to his prejudice. This assignment of error is overruled. :
[6] Next the defendant contends that the trial court erred in instructing the jury that in order to find that defendant could not form a specific intent to commit a felony (in the felony-murder portion of the charge) or that the defendant was mentally incapable of premeditation and deliberation (in the statutory first-degree murder portion of the charge) that they must find that the defendant was “utterly incapable” (or “utterly unable”) of forming a specific intent. Defendant contends that this was a shifting of the burden of proof and that it placed too heavy a burden upon him.
In the felony-murder instruction, the trial judge told the jury that they could not convict the defendant under this theory if they found “that he was utterly incapable of forming the felonious intent” to commit robbery. (Emphasis supplied.) In the alternative instruction on statutory first-degree murder (requiring the proof of the elements of premeditation and deliberation) the court likewise told the jury that they could not *445convict the defendant of murder in the first degree if they found “that he was utterly incapable of forming the specific intent to kill or to plan and design the doing of that act, . . (Emphasis supplied.) The court stated that under such circumstances “he would have been mentally incapable of premeditating and deliberating.”
In the present case defendant offered evidence tending to show that he was intoxicated by the drug Valium and by the alcoholic beverage beer. It was essentially on this basis the defendant contended that the State had failed to prove he had the requisite intent under the alternative charges.
“The rule that voluntary intoxication is not a general defense to a charge of crime based on acts committed while drunk is so universally accepted as not to require the citation of cases.” 8 A.L.R. 3d 1236 at 1240 (“Modern Status of the Rules as to Voluntary Intoxication as Defense to Criminal Charge”). In some jurisdictions the jury is not allowed to consider voluntary intoxication even on issues of specific intent. Id. at 1241. Another writer concludes, “Of course, intoxication itself does not preclude a finding that the requisite mental element was present, unless it was so extreme as to render the accused entirely incapable of the state of mind required. Where the offense is one requiring a specific intent, evidence of voluntary intoxication is admissible and may be considered in determining whether such specific intent was actually present, although it acts as a complete defense only where the degree of intoxication is such as to render the accused incapable of entertaining the specific intent.” (Emphasis supplied.) 21 Am. Jur. 2d § 107, 186.
In State v. Propst, 274 N.C. 62, 72, 161 S.E. 2d 560, 567 (1968) our Court enunciated the following rule: “[I]f it be shown that an offender, charged with such crime, is so drunk that he is utterly unable to form or entertain this essential purpose, he should not be convicted of the higher offense.” (Emphasis supplied.) The able trial judge followed the guideline of Propst explicitly. The contention of the defendant that the burden of proof was shifted is incorrect. The burden of proving specific intent was properly placed upon the State in the instruction. The words used by the court, “utterly incapable,” merely related to the degree of intoxication and not to the shifting of the burden. The jury certainly understood that the court meant that the defendant must have lost control of his mind through intoxication in order to be unable to form the *446 specific intent. This assignment of error is without merit and is overruled.
[7] Finally, defendant contends that the trial court committed error in its instruction on first-degree murder under the premeditation and deliberation theory when it told the jury that they could consider the “dealing of lethal blows after the deceased had been felled and rendered helpless” on the ground that there was no evidence of such blows and to so instruct would be interpreted as an expression of opinion by the presiding judge.
As Justice Sharp (now Chief Justice) said in State v. Van Landingham, 288 N.C. 589, 599, 197 S.E. 2d 539, 545 (1973) : “Ordinarily it is not possible to prove premeditation and deliberation by direct evidence. These facts must be established by proof of circumstances from which they may be inferred. Among the circumstances to be considered in determining whether a killing was with premeditation and deliberation are: want of provocation on the part of the deceased; the conduct of the defendant before and after the killing; the use of gross excessive force, or the dealing of lethal blows after the deceased has been felled.” (Emphasis supplied.) See State v. Walters and cases cited therein, 275 N.C. 615, 623-24, 170 S.E. 2d 484, 490 (1969). See also State v. Buchanan, 287 N.C. 408, 422, 215 S.E. 2d 80, 88 (1975).
Judge Fountain’s instructions on circumstantial evidence to be considered in determining whether there was premeditation and deliberation are almost identical to those used by our Court in Van Landingham with the deletion of any reference to gross and excessive force as a factor. Moreover, in this case there was sufficient evidence upon which to base the instructions given. The record bears out a want of provocation. The defendant’s own testimony indicated that the deceased had done nothing to make him angry and that in fact he had been nice to him. There was evidence of unusual conduct on the part of defendant before and after the killing. In particular, the purchase of the pistol, the demand to stop the cab, and the flight of the defendant from the scene of the shooting indicated that the defendant had a plan. The firing of two or more shots at close range under the circumstances admitted by defendant would certainly be considered the use of unnecessary force.
The defendant particularly objects to that portion of the charge stating that one of the factors to be considered was “the *447dealing of lethal blows after the deceased had been felled and rendered helpless.” Defendant contends that there is no evidence of this circumstance. The record is to the contrary. The evidence indicated that one shot was fired into the front of deceased’s neck and that another was fired into the back of his head. Defendant testified that the deceased was in front of him when he fired and that there was a lapse of seconds between shots. Certainly one explanation of the bullet wound in the back of the head is that it was fired after the deceased was shot the first time and had fallen to the ground. The defendant testified that he did not remember if he shot the deceased in the back of the head after he fell. See State v. Buchanan, supra, for a similar instruction where there was no evidence of a blow after deceased fell. This assignment of error is overruled.
Defendant’s court-appointed counsel have with diligence searched the record and made numerous assignments of error. The argument and the brief of the Attorney General’s office have ably answered each assignment of error. Because this is a capital case, we have carefully considered all of the assignments and conclude that there is
No error.
Justices Lake and Exum concur in the result.
