The defendant appeals from his conviction of murder in the first degree of Bruce R. Cullen in August, 1970. The judge charged the jury on the theories of deliberate premeditation and extreme atrocity or cruelty as the bases for a conviction of murder in the first degree. Except for his general claim for relief under G. L. c. 278, § 33E (1986 ed.), the defendant’s appellate arguments are all directed to alleged errors in the judge’s jury instructions, none of which was the subject of an objection at trial. We, therefore, consider each of these challenges only to determine whether there was a substantial likelihood of a miscarriage of justice (G. L. c. 278, § 33E), recognizing that constitutionally based arguments that apply to this trial are fully before us. We affirm the conviction.
Only a brief recitation of the evidence that the jury could have believed need be recounted. The defendant stabbed the victim nine times during a brawl among several young men in front of an apartment building in South Boston on August 9, 1970. There was evidence that the codefendant, who was found not guilty, had held the victim while someone stabbed him. After the stabbing, the defendant made several damaging admissions to various acquaintances. There was evidence that the defendant had consumed alcohol, marihuana, and perhaps “diet pills” shortly before the incident.
The defendant was tried and convicted in 1971. The reasons why his appeal did not arrive at this court until eighteen years later are not fully apparent on the record before us. A close inspection of the circumstances would probably show at least a lack of diligence by the defendant, his former counsel, and representatives of the Commonwealth. If we were to order a new trial, the defendant might well be justified in claiming that the passage of time has prejudiced his right to a fair trial. The passage of time has probably also prejudiced the Commonwealth’s ability to present a case on retrial. There is, however, no basis for granting a new trial.

The defendant’s appeal, on the other hand, has not been prejudiced in its quality or force because of the passage of time. See
Commonwealth
v.
Hudson,
1. The judge’s charge on reasonable doubt did not unconstitutionally diminish the Commonwealth’s burden of proof. The judge gave two examples of situations in which, although one could not be absolutely certain that a fact was true, a finding of that fact beyond a reasonable doubt would be warranted. The examples were appropriate in demonstrating that proof beyond all doubt was not required.
The judge’s reference to proof beyond a reasonable doubt as requiring proof “to that degree of certainty upon which you would act in the important affairs of your own life,” without his
*234
making any accompanying reference to specific examples, is not ground for reversal. See
Commonwealth
v.
Garcia,
The claim that the judge unfairly focused the jury’s attention on the consequences of failing to convict a person shown to be guilty beyond a reasonable doubt is not supported by a reading of the charge as a whole. The charge forcefully balanced the defendant’s rights against those of the Commonwealth. We conclude that the instruction on reasonable doubt, viewed as a whole, was free of error. See
Commonwealth
v.
Festa,
2. The judge could have better distinguished for the jury between the “intention to kill” prong of malice aforethought and deliberate premeditation. We have recognized that a jury charge equating deliberate premeditation with an intent to kill (which would constitute malice) could make unjustifiable a conviction of murder in the first degree. See

Commonwealth
v.
Perry,
4. The defendant challenges the portion of the judge’s charge that said “[mjalice is implied in every deliberate cruel act
*235
by one against another.” He claims that the judge’s words created an unconstitutional presumption of malice if the jury found that the defendant committed a deliberate cruel act against the victim. See
Francis
v.
Franklin,
The judge’s statement was too broad as applied to all deliberate cruel acts. When, however, it is considered as applied to a victim stabbed severely nine times, the act of the perpetrator would be intentional and cruel (which, we take to mean, in part, unprovoked or not in self-defense), and would imply malice. In the context of the facts of this case and in light of the judge’s entire instruction on malice (which is not otherwise challenged), we see neither a substantial likelihood of a miscarriage of justice calling for relief under G. L. c. 278, § 33E, nor an unconstitutional presumption dictated to the jury.
5. At oral argument the defendant raised a point not presented at the trial or in his appellate brief. He complains that the judge improperly shifted the burden of proof to the defendant on the issue of the existence of provocation that would negate a finding of malice and thus would justify only a verdict of guilty of manslaughter. See
Mullaney
v.
Wilbur,
The circumstances in which the defendant came to stab the victim are so sketchy that an instruction on provocation was probably given only as an excess of caution. Contrast
Commonwealth
v.
Boucher,
*236 The judge had told the jury that the Commonwealth had to prove the elements of murder beyond a reasonable doubt. He further explained that provocation negated malice. Contrast Commonwealth v. Boucher, supra at 661-663. The judge’s use of finding language “within a realm of what I have explained to you” does not constitute unconstitutional burden shifting nor does it raise a substantial likelihood of a miscarriage of justice where, on proper instructions, the jury found either deliberate premeditation, extreme atrocity or cruelty, or both.
6. The defendant seeks relief under G. L. c. 278, § 33E, on the ground that there was evidence that he was highly intoxicated at the time of the crime and because there was no eyewitness who identified him as the person who wielded the knife.
The judge did not tell the jury that they could not consider the defendant’s degree of intoxication in determining whether the Commonwealth had proved each element of the crime beyond a reasonable doubt. He correctly told the jury that the voluntary consumption of alcohol was not an excuse. 3
The defendant argues correctly that the motives of the persons who presented incriminating evidence against him were suspect and that much of the evidence against him was subject to serious challenge. These arguments were for the jury to weigh. In performing our § 33E function, we do not act as a second jury.
This case involves a senseless brawl, fueled by alcohol and other drugs. The defendant and the victim were strangers. Had there been but one stab wound, we might well have regarded this case as one of a class not typically involving murder in the first degree. See
Commonwealth
v.
Keough,
In fulfilling our § 33E function, we decline to order a new trial or to direct that a verdict of a lesser degree of guilt be entered. We affirm the judgment and remand the defendant’s motion under rule 30 to the Superior Court for consideration.
So ordered.
Notes
The defendant filed in this court a motion under Mass. R. Crim. P. 30,
The defendant is entitled to consideration of his rule 30 motion at the trial level. We shall remand that motion to the Superior Court for consideration. Among the elements to consider will be the lack of diligence, if any, of the defendant. It may be difficult to produce anything other than public records bearing on most aspects of the slow course of the appeal. Trial counsel is deceased, as is the trial judge.
The judge said “if you find within a realm of what I have explained to you with regard to manslaughter, if you find there was provocation and that provocation cannot only be by words, but if there was provocation extreme *236 enough to palliate and reduce this crime, you may find, a fifth possible verdict, guilty of manslaughter.”
The judge did tell the jury that a defendant’s knowledge was not relevant in deciding whether a murder was committed with extreme atrocity or cruelty and that, on this point, his intoxication, if any, played no part in the jury’s determination. That was a correct statement of the law at the time. See
Commonwealth
