    Indictment found and returned in the Superior Court
    Department on December 9, 2010.
    The case was tried before Thomas F. McGuire, Jr., J.
    Theodore F. Riordan (Deborah Bates Riordan with him) for
    the defendant.
    Tara L. Blackman, Assistant District Attorney, for the
    Commonwealth.
    SPINA, J.     On October 20, 2010, the defendant stabbed the
    victim six times with a small folding pocket knife, killing him.
    The Commonwealth's theory of motive was that both men had been
    2
    vying for the affection of the same woman.    The primary dispute
    at trial was whether the victim was the first aggressor, whether
    the defendant acted in self-defense, and who first had
    possession of the knife.    The jury convicted the defendant of
    murder in the first degree on a theory of extreme atrocity or
    cruelty.   On appeal the defendant asserts error by trial
    counsel, by the prosecutor, and by the judge.    He claims that
    trial counsel was ineffective (1) for making an incorrect
    argument about voluntary manslaughter (which he asked the jury
    to find), and (2) for failing to request an instruction on
    involuntary manslaughter.    The defendant argues that the
    prosecutor improperly cross-examined him on his right to remain
    silent, including (1) questions about why he had not gone to
    police with his version of events, (2) questions about his
    failure to tell his grandmother and friends that he was
    defending himself, and (3) questions that emphasized his failure
    to tell anyone his version of events until trial.    The defendant
    also contends that the prosecutor (4) improperly appealed to the
    sympathy of the jury in his closing argument, and (5) made
    improper argument about the defendant's failure to call
    witnesses to corroborate his testimony.    The defendant asserts
    that the judge erred (1) by failing to instruct the jury that
    the Commonwealth must disprove the absence of excessive force in
    self-defense, and (2) by giving an incorrect instruction on
    3
    self-defense.   We conclude that the combined effect of the
    prosecutor's closing argument and trial counsel's failure to
    request a voluntary manslaughter instruction based on reasonable
    provocation requires that the defendant be given a new trial.
    However, we give the Commonwealth the option of either accepting
    a reduction of the verdict to manslaughter, or having the
    conviction vacated and proceeding with a new trial.
    1.    Background.    The jury could have found the following
    facts.    We reserve other details for discussion of specific
    issues.   The defendant was incarcerated on an unrelated matter
    from about the middle of August, 2010, until October 15, 2010.
    While he was incarcerated, the defendant wrote a letter to a
    woman named Lisa whom he had started dating in June.     In the
    letter he confessed that he thought she was "perfect."    During
    the defendant's incarceration the victim took notice of Lisa and
    began flirting with her.    After the defendant was released from
    his incarceration he learned of the developing relationship
    between the victim and Lisa.     This angered the defendant, who
    told a friend that the next time he saw the victim he was going
    to punch him in the head.    On October 19, 2010, the defendant
    and Lisa socialized with another couple until about 11 P.M.        At
    one point the defendant and Lisa became involved in a mild
    argument over the victim.     The two couples agreed to get
    together the next day.
    4
    The two couples met at about 2 P.M. on October 20, as
    planned.   At about 7:30 P.M. they went to a soup kitchen in New
    Bedford because Lisa had forgotten her key to the addiction
    recovery house for women where she was staying, and other
    residents of the recovery house were at the soup kitchen
    attending an Alcoholics Anonymous meeting.     She planned to
    borrow a key from one of the residents who was at the meeting.
    The victim was at the meeting.    The defendant and Lisa appeared
    to be having a serious conversation.
    During a break in the meeting the defendant walked over to
    the victim and said he had been hearing things that the victim
    was saying about him, and he felt "disrespected."    The defendant
    then started punching the victim in the head.    The victim tried
    to deflect the blows and backed away.    The defendant started
    chasing and lunging at the victim.     He stabbed the victim six
    times with a small folding pocket knife, a type of knife the
    defendant owned.     The incident lasted no more than thirty
    seconds.   The defendant left the scene with the people who had
    arrived with him.    As they were driving, the defendant said that
    he had stabbed the victim, adding, "I hope I didn't kill him."
    The victim died later that night from his wounds, which included
    two puncture wounds to the heart and one that completely passed
    through the liver.
    5
    The defendant threw the knife into a wooded area.   It was
    later recovered by police.    The defendant's friends left him at
    a supermarket where he telephoned his grandmother.      He asked her
    to give him a ride.    The defendant's grandmother drove him to
    the home of one of his close friends.    He told one of the people
    living there that he had gotten into a fight over a girl with
    someone at the soup kitchen.    He said that he and the other man
    got into a fist fight, and that the other man got the better of
    him.    The defendant said that he went to the vehicle in which he
    had arrived, retrieved a knife, and then "slashed" the other man
    in the chest two or three times.    He said that he did not know
    if the other man was still alive.    This person heard him make
    several telephone calls trying to find out if the other man was
    alive.    The defendant seemed very worried.
    Police went to the friend's house looking for the defendant
    at approximately 2 A.M. on October 21, 2010.      They found him
    hiding in a cubby hole in a rear hallway.      He was placed under
    arrest.    Police observed a fresh cut on the defendant's right
    hand between the webbing of his right index finger and his
    thumb.    They also observed three fresh cuts on his left hand,
    two of which were between the webbing of his index finger and
    his thumb, and the third was on the pad of this thumb.
    A friend with whom the defendant had socialized on October
    19 and 20, 2010, testified for the defense.      He said that the
    6
    victim threw the first punch.   He also testified that about two
    months before the killing, the victim had threatened to stab the
    defendant.   The defendant testified in his defense.    He said
    that he was fearful of the victim, who was known as a "tough
    guy," and referred to as "Big Mike."     The victim was "a lot
    bigger" and ten years older than the defendant.     He said that he
    wanted to resolve their issues by talking when other people were
    nearby.   He testified that the victim started punching him and
    then pulled out a knife.   The defendant grabbed the blade of the
    knife and pulled it out of the victim's hand.1    The victim came
    after him and tried to grab him.   The defendant swung the knife
    "wildly" in order to defend himself.     He said that he did not
    realize that he was stabbing the victim, or that the victim
    might be seriously hurt, and that he broke down in tears over
    the incident.   He said that he never intended to kill the
    victim.
    The defendant testified that he once owned a similar knife,
    but not at that time.   He said that the knife that was involved
    in the stabbing was not his, and that he did not recall telling
    anyone that the fight was over a girl.     He denied going back to
    the car in which he arrived at the soup kitchen to get the
    1
    There is no dispute that deoxyribonucleic acid (DNA)
    testing on the knife handle and blade revealed blood from at
    least two individuals, that the defendant's DNA matched the
    major profile, and that the victim was a potential contributor
    of the minor profile.
    7
    knife, and he said that he had no recollection of telling anyone
    that he did so.   He testified that the victim had threatened to
    stab him about two months before the stabbing.
    2.   Ineffective assistance of counsel.     The defendant first
    contends that trial counsel was ineffective for failing to
    request a jury instruction on involuntary manslaughter, based on
    his testimony that he did not intend to kill the victim.      See
    Commonwealth v. Whitman, 
    430 Mass. 746
    , 753 n.13 (2000)
    (involuntary manslaughter involves unintentional unlawful
    killing).   We need not dwell on this issue.    The defendant cites
    no authority in support of this argument.      The blade of the
    knife used to kill the victim penetrated the victim's body to a
    depth greater than the length of the blade.     The Commonwealth's
    pathologist testified that this can occur when the force with
    which the knife is thrust into the body compresses the rib cage.
    The force was so great that the knife blade went completely
    through the victim's liver.   The victim had been stabbed six
    times, including in the chest, back, and side.     In comparable
    circumstances, this court has said that an onslaught of this
    degree does not support a finding that the killing was
    unintentional, notwithstanding a defendant's statement that he
    did not intend to kill the victim.   A request for an involuntary
    manslaughter instruction properly would have been denied.     See
    Commonwealth v. Tague, 
    434 Mass. 510
    , 518-519 (2001), cert.
    8
    denied, 
    534 U.S. 1146
    (2002); Commonwealth v. Dunton, 
    397 Mass. 101
    , 103 (1986); Commonwealth v. Golston, 
    373 Mass. 249
    , 260
    (1977), cert. denied, 
    434 U.S. 1039
    (1978).    Counsel was not
    ineffective for failing to request an instruction that was not
    warranted by the evidence.   See Commonwealth v. Leng, 
    463 Mass. 779
    , 788 (2012).
    The defendant next argues that counsel was ineffective for
    making a legally incorrect and confusing argument on self-
    defense and voluntary manslaughter.2    He contends that trial
    counsel urged the jury to find the defendant guilty of
    manslaughter because he had acted in self-defense.    The correct
    statement of law, he maintains, would have been that the
    defendant should be convicted of manslaughter because he had
    used excessive force in self-defense.    However, he continues,
    trial counsel argued self-defense, which should have culminated
    in a request for a verdict of not guilty.     Counsel was
    ineffective, the defendant concludes, because he failed to
    explain why the verdict should be manslaughter.
    The defendant misstates trial counsel's argument.      Trial
    counsel never used the term "self-defense" in his argument, and
    2
    A claim of ineffective assistance of counsel made on the
    trial record alone, as here, "is the weakest form of such a
    challenge because it is bereft of any explanation by trial
    counsel for his actions and suggestive of strategy contrived by
    a defendant viewing the case with hindsight." Commonwealth v.
    Peloquin, 
    437 Mass. 204
    , 210 n.5 (2002).
    9
    he expressly said that he was not asking the jury to find the
    defendant not guilty.   The argument was purely factual.    Counsel
    argued that the significant variations in the eyewitness
    testimony were understandable because there were many people
    milling about and conversing in small groups during a break in
    the Alcoholics Anonymous meeting.   The various witnesses caught
    different and only partial glimpses of this very brief incident.
    In most instances, the glimpse that a witness caught was in his
    or her peripheral vision.   As a result, no one witness saw the
    entire incident, and there were obvious flaws in some
    perceptions of what occurred.   The culmination and thrust of the
    argument was that there was one fact that was not in dispute,
    and that was that the defendant sustained cuts on his hands, and
    his blood was found on the knife.   This could only be explained,
    he reasoned, by the defendant's testimony that the victim was
    the one who introduced the knife to the fray, and the
    defendant's hands were cut as he wrested it away from him.
    Counsel also argued, based on the testimony of the defendant's
    friend, that the victim had been the first aggressor.      Although
    counsel never used the words "self-defense" or "excessive use of
    force in self-defense," it is readily apparent that counsel was
    urging the jury to find that the defendant, armed with the knife
    he had taken from the victim, used excessive force in self-
    defense while the victim continued to pursue him.
    10
    This was not a model closing argument, but it was adequate.
    Counsel's decision to focus on the single fact that was
    essential to the jury's acceptance of his manslaughter theory,
    namely, the victim's introduction of lethal force, without
    discussing the applicable law, was not a manifestly unreasonable
    strategy.   See Commonwealth v. Adams, 
    374 Mass. 722
    , 728 (1978)
    (tactical decision of counsel will not constitute ineffective
    assistance unless it was manifestly unreasonable when made).
    Counsel reasonably could have thought that a brief closing that
    concentrated on the most critical fact for the defense would
    emblazon the importance of that fact on the minds of the jurors
    and become the centerpiece of their deliberations.    He
    reasonably could have anticipated that in short order his
    closing would play directly into what the judge would instruct
    the jury on self-defense and use of excessive force in self-
    defense, and that it would be more beneficial to concentrate on
    the facts without a discussion of the law.
    Typically (and properly), lawyers are permitted some leeway
    during closing argument to discuss the law as it pertains to
    their case, to give context to the facts they argue, but they
    are not required to do so.   Cf. Commonwealth v. Jones, 
    432 Mass. 623
    , 628 (2000) ("Prosecutors and defense counsel must restrict
    their closing arguments to the evidence and [permissible]
    inferences that can be drawn from the evidence").    However,
    11
    lawyers may not misstate principles of law in closing argument.
    See Commonwealth v. Thomas, 
    401 Mass. 109
    , 113 (1987).    The
    prosecutor barely discussed the law in his closing argument.
    Counsel's decision to leave the jury with the factual crux of
    the defense, without comment on the law, did not amount to
    ineffective assistance.
    3.   Cross-examination of the defendant.    The prosecutor
    cross-examined the defendant about his failure to tell civilian
    witnesses that he was defending himself, his failure to contact
    police prior to his arrest and tell them that he was acting in
    self-defense, and whether the first time that he told anyone
    that he was defending himself was at trial.    The defendant
    argues that these questions constituted improper comment on his
    right to remain silent, and that a new trial is required.       See
    Doyle v. Ohio, 
    426 U.S. 610
    , 619 (1976); Commonwealth v. Person,
    
    400 Mass. 136
    , 140 (1987).   There was no objection, so we review
    under the standard of a substantial likelihood of a miscarriage
    of justice.   See Commonwealth v. Wright, 
    411 Mass. 678
    , 681
    (1992), S.C., 
    469 Mass. 447
    (2014).
    During his direct examination the defendant testified that
    he had approached the victim.   The victim "snapped" at him, and
    then threw a punch at him.   The victim then produced the knife,
    but the defendant grabbed it from him.   The victim came at the
    defendant, who swung "wildly" at the victim to try to keep him
    12
    at bay.   The defendant testified that he did not realize that he
    was stabbing the victim, and that he did not intend to kill him.
    Later, he called for his grandmother to pick him up.   He was in
    shock and was crying over what had happened.   On cross-
    examination the defendant said that he learned that the victim
    had been hurt badly and that he was concerned for the victim, as
    well as for himself.   He telephoned a number of people trying to
    find out how the victim was doing, and what kind of trouble he
    might be facing.
    Earlier in the trial a Commonwealth witness had testified
    that the defendant came to the house of a friend, where the
    witness had been staying.   The defendant appeared worried, and
    the witness asked him what had happened.    The defendant
    described the encounter with the victim, as previously
    discussed, including an admission that he, the defendant, went
    to the vehicle in which he arrived and obtained a knife.      The
    defendant also made statements about the stabbing as he and
    others drove from the scene.
    This was not a case in which the defendant was confronted
    with his prearrest silence.    See, e.g., Commonwealth v.
    Nickerson, 
    386 Mass. 54
    (1982).   This was a case where the
    prosecutor was confronting the defendant with his prearrest
    statements, and impeaching him with inconsistencies between
    those statements and his trial testimony.   The defendant never
    13
    mentioned in his prearrest statements that he had acted in self-
    defense or that the victim was the first aggressor.    The
    prosecutor was entitled to cross-examine the defendant about
    those inconsistencies, including any omissions in those
    statements that were different from his trial testimony.     See
    Commonwealth v. Hesketh, 
    386 Mass. 153
    , 161 (1982).     An omission
    in a prior statement may render that statement inconsistent
    "when it would have been natural to include the fact in the
    initial statement."   Commonwealth v. Ortiz, 
    39 Mass. App. Ct. 70
    , 72 (1995).   See Commonwealth v. Perez, 
    460 Mass. 683
    , 699
    (2011); Mass. G. Evid. § 613(a)(2) & notes (2015).     Where the
    defendant had been worried about the fate of the victim, as well
    as his own legal fate, it would have been natural to explain
    that he was acting in self-defense when describing the incident
    in his prearrest statement to civilian witnesses.     The
    prosecutor acted appropriately when cross-examining the
    defendant about what he told and what he did not tell civilian
    witnesses.
    The prosecutor's cross-examination of the defendant about
    his failure to seek out police to report that the victim might
    be in need of medical attention, and to tell them he acted in
    self-defense, was not proper.   Although the prosecutor might
    properly have cross-examined the defendant about his "concern"
    for the victim by asking if he called for an ambulance, it would
    14
    not have been natural for him to seek out police to tell his
    exculpatory story.   Compare Commonwealth v. Barnoski, 
    418 Mass. 523
    , 536 (1994).   This was error, but we conclude that it did
    not create a substantial likelihood of a miscarriage of justice.
    The defendant had made several prearrest statements to friends
    in which he made no reference to self-defense.     We are satisfied
    that questions about his failure to seek out police to say he
    acted in self-defense added little, if anything, to the impact
    on the jury of the several statements he made to his friends in
    which he made no mention of self-defense.    Moreover, the
    prosecutor did not mention the matter in his closing argument,
    thus keeping any prejudice at a minimum.     See 
    id. at 537
    n.7.
    4.   Prosecutor's closing argument.     The defendant contends
    that the prosecutor made improper closing argument by appealing
    to the sympathy of jurors, and by arguing that the defendant
    failed to call witnesses to testify about the victim's
    reputation for violence.    Because the defendant did not object
    to the prosecutor's argument, our review is under the standard
    of a substantial likelihood of a miscarriage of justice.     See
    
    Wright, 411 Mass. at 681
    .   In making that determination, the
    cumulative effect of all the errors must be "considered in the
    context of the arguments and the case as a whole."     Commonwealth
    v. Maynard, 
    436 Mass. 558
    , 570 (2002).      If a defendant
    establishes that the prosecutor's closing argument was improper,
    15
    we are guided by the following factors when deciding whether a
    new trial is required:   "whether 'defense counsel seasonably
    objected to the arguments at trial . . . whether the judge's
    instructions mitigated the error . . . whether the errors in the
    arguments went to the heart of the issues at trial or concerned
    collateral matters . . . whether the jury would be able to sort
    out the excessive claims made by the prosecutor . . . and
    whether the Commonwealth's case was so overwhelming that the
    errors did not prejudice the defendant.'"   
    Id., quoting Commonwealth
    v. Santiago, 
    425 Mass. 491
    , 500 (1997), S.C., 
    427 Mass. 298
    , and 
    428 Mass. 39
    , cert. denied, 
    525 U.S. 1003
    (1998).
    See Commonwealth v. Kozec, 
    399 Mass. 514
    , 516-518 (1987).
    The prosecutor's argument covered thirty pages of the trial
    transcript.   For the most part, it was highly structured and
    grounded in the trial record.   About one-third of the way
    through his closing, when discussing the defendant’s testimony
    that he was "scared" of the victim, that the victim was bigger
    and ten years older, and that the victim had a reputation as a
    "tough guy," the prosecutor argued as follows:
    "Bad guy, tough guy, bad reputation. Where's the evidence
    of that? Only out of his mouth. And when you consider the
    credibility of witnesses in this case, you have to consider
    bias, motive to lie. Who has the biggest interest in the
    outcome of this case? This guy. He's the one on trial.
    He's the one who wants to make you think poorly of [the
    victim]. Because that helps him. Because then that starts
    to make you think maybe the guy wasn't such a good guy.
    16
    Maybe this isn't such a big deal.      There's no evidence of
    that." (Emphases added.)
    The defendant contends that the argument constituted an improper
    missing witness argument.   There is some force to the claim.
    The argument implies, among other things we will discuss
    shortly, a failure to call witnesses on the question of the
    identity of the first aggressor.     As such, it was improper
    because the prosecutor did not first obtain judicial approval to
    make a missing witness argument, see Commonwealth v. Pena, 
    455 Mass. 1
    , 16-17 (2009), and Mass. G. Evid. § 1111(a) (2015), and
    because testimony from third-party witnesses regarding the
    victim’s reputation would not be admissible.    See Commonwealth
    v. Adjutant, 
    443 Mass. 649
    , 664-665 (2005) (testimony by third-
    party witnesses as to victim’s reputation for violent behavior
    to establish that victim was first aggressor is inadmissible).
    We discern another flaw in this argument.      A prosecutor may
    argue that a testifying defendant has an interest in the outcome
    of a case and his credibility may be scrutinized on that basis,
    see Commonwealth v. Ortega, 
    441 Mass. 170
    , 181-182 & n.19
    (2004), but the argument must be understated and approached
    cautiously.   Here, it was not.    The clear premise of the
    prosecutor's argument is that the defendant's testimony, because
    he was the defendant and on trial, did not even qualify as
    evidence because it was inherently incredible.    The argument was
    17
    patently improper.    Cf. Commonwealth v. Scesny, 
    472 Mass. 185
    ,
    201-202 (2015) (prosecutor improperly described evidence
    introduced by defendant as not material or relevant and
    therefore not to be considered as evidence).
    Toward the end of his argument the prosecutor focused on
    the Cunneen factors that must be considered on the question of
    extreme atrocity or cruelty.   They are: indifference to the
    victim's suffering, the consciousness and degree of suffering of
    the victim, the number of stab wounds and physical punches
    thrown, the manner and force with which the stab wounds were
    inflicted, and the disproportion between the means needed to
    cause death and those employed.    See Commonwealth v. Cunneen,
    
    389 Mass. 216
    , 227 (1983).   This part of the prosecutor's
    closing was very powerful, and proper.    The prosecutor should
    have stopped there.   He ended his closing argument with a highly
    improper, emotionally charged discussion covering three pages of
    transcript.
    The prosecutor built upon the Cunneen factors.     He
    commented that the civilian witnesses, who were "at the wrong
    time at the wrong place," tried to save the victim, only to
    "[see] the color run right out of him, right down to gray.     And
    they saw him struggling and bleeding in front of his own
    father."   The emotional impact on witnesses of the victim's
    death was not a proper matter for consideration by the jury.       In
    18
    contrast to the defendant's indifference, the prosecutor
    developed a mantra of how "[the victim's] life mattered" to his
    family, to the civilians who tried to save him, to the
    paramedics who summoned heroic effort to try to save this "total
    stranger," to the police who investigated the case, and "to all
    of us."   He ended with a statement that the victim "has as much
    right . . . [to live as] this defendant . . . has an absolute
    right to a fair trial. . . .   [The victim] had a
    [c]onstitutional right to live, to pursue whatever means of
    happiness he chose to pursue.[3] . . .   [H]e was a human being
    just like any of us, and . . . there was an inherent value to
    his life just like any of our lives."    He asked the jury, on
    behalf of the Commonwealth, to return "a fair and just verdict,"
    adding that the victim "asks for no more, but he deserves
    nothing less," because the defendant "chose . . . to end the
    life of [the victim]" out of "anger."
    It is improper for a prosecutor to characterize a criminal
    trial as a dispute between a deceased victim on the one hand,
    and the defendant on the other, and to exhort the jury to
    dispense justice evenly between them.    The deceased is not a
    party to the case.   A criminal trial places the interests of the
    Commonwealth and the defendant against one another.    An argument
    3
    The prosecutor had argued earlier that the victim "had
    every right to have an acquaintance with Lisa Weaver, as well as
    she did" with the victim.
    19
    that asks the jury to give justice to the victim is an improper
    appeal to sympathy for the victim.     See Commonwealth v.
    Drumgold, 
    423 Mass. 230
    , 253 (1996).    The prosecutor's improper
    call to justice for the victim was aggravated by his inclusion
    of the paramedics and the civilian witnesses to the victim's
    last moments in his appeal to sympathy.    Similarly, the
    prosecutor's argument that the victim's life mattered, and that
    the victim had a constitutional right to live, were improper
    appeals to sympathy.    See Commonwealth v. Torres, 
    437 Mass. 460
    ,
    464-465 (2002).
    These improprieties were not just fleeting comments or
    minor aspects of his closing argument, nor were they the type of
    afterthought that we have said does not require reversal.     See,
    e.g., Commonwealth v. Judge, 
    420 Mass. 433
    , 451-452 (1995)
    (single improper sentence appealing to sympathy does not require
    new trial).   The improper comments at the end of the closing
    comprised a structural segment, indeed, the denouement of the
    prosecutor's closing.    This section of his argument was
    integrated into his argument of the Cunneen factors,
    particularly the defendant's indifference to the victim's
    suffering.    The juxtaposition of the defendant's indifference
    with the effect of the killing on the paramedics, the civilian
    witnesses, the police, and "all of us," for whom the victim's
    life "mattered," was demonstrably improper.     It suggested that
    20
    everyone's collective concern for the victim's life was a
    legally relevant consideration of and, by way of contrast, an
    illumination of the defendant's indifference to the victim's
    suffering.   Although jurors may be credited as having a "certain
    measure of . . . sophistication in sorting out excessive
    claims," 
    Kozec, 399 Mass. at 517
    , the suggestion here was that
    they properly and logically could consider the evidence of
    heroic and humanitarian efforts to save the victim, and the
    rhetoric of how his life "mattered" to everyone except the
    defendant, on the question of the defendant's indifference to
    the victim's suffering.   The judge's general instructions on
    evidence, sympathy, and arguments of counsel did not dispel that
    notion.   See 
    Santiago, 425 Mass. at 501
    .   He did not
    specifically address the prosecutor's improprieties, which were
    hard driving and sustained, and which went to a critical aspect
    of the case.   The prosecutor's argument far overshadowed the
    defendant's assertion at trial that he was concerned for the
    victim and did not realize that he was stabbing him.
    The portion of the argument that presumed that the
    defendant was not credible because he was on trial challenged
    the heart of the defense, namely, the defendant's credibility as
    to who was the initial aggressor, who produced the knife, and
    whether the defendant had acted in self-defense.    Again, the
    21
    judge's general instructions did not adequately address the
    error.
    Although there was no objection, which is some indication
    of the level of prejudice, that is not dispositive.
    Commonwealth v. Toro, 
    395 Mass. 354
    , 360 (1985).     The
    Commonwealth's case was strong, but it was not overwhelming.      We
    have serious concerns about the effect of the improprieties in
    the prosecutor's closing argument on the jury's deliberations.
    We need not decide if they created a substantial likelihood of a
    miscarriage of justice because we have identified another error
    in the course of our plenary review that, in combination with
    the errors in the prosecutor's closing argument, require a new
    trial.    That error is discussed in the final section of this
    opinion.
    5.     Jury instructions.   The defendant asserts error in the
    jury instructions.    We address them because they may arise on
    remand.    First, he argues that the judge failed to instruct the
    jury that in order to return a verdict of guilty of murder, the
    jury must find that the Commonwealth proved beyond a reasonable
    doubt the absence of mitigating circumstances, specifically, the
    absence of excessive force in self-defense.     Second, the
    defendant contends that the instruction on manslaughter was
    flawed because it used permissive language that failed to
    require the jury to find manslaughter if the defendant used
    22
    excessive force in self-defense, and because it inconsistently
    stated that the jury should consider manslaughter only if the
    defendant lawfully was acting in self-defense.    There were no
    objections to the judge's instructions.
    The Model Jury Instructions on Homicide (1999) in effect at
    the time of the trial of this case, at page 27, contain the
    instruction that "[i]n order to obtain a conviction of murder,
    the Commonwealth must prove beyond a reasonable doubt the
    absence of . . . mitigating circumstances," including "excessive
    use of force in self-defense."   The judge did not include this
    instruction, and he should have included it.     However, the judge
    twice instructed the jury that to obtain a conviction of murder
    the Commonwealth must prove beyond a reasonable doubt that the
    defendant did not act in self-defense, and if it failed to do
    so, then they must find the defendant not guilty.    The judge
    also instructed that if the Commonwealth proved beyond a
    reasonable doubt that the defendant used excessive force in
    defending himself (the judge defined excessive force in self-
    defense), then the jury should return a verdict of guilty of
    voluntary manslaughter.   This was a correct statement of law.
    See Commonwealth v. Glacken, 
    451 Mass. 163
    , 167 (2008);
    Commonwealth v. Williams, 
    450 Mass. 879
    , 885 n.4 (2008);
    Commonwealth v. McLaughlin, 
    433 Mass. 558
    , 563 (2001);
    Commonwealth v. Little, 
    431 Mass. 782
    , 787 (2000); Commonwealth
    23
    v. Boucher, 
    403 Mass. 659
    , 663 (1989).       It also conformed with
    the Model Jury Instructions on Homicide (1999), at page 30.
    There was no error, but we urge judges to adhere to the model
    instructions on homicide.       On remand, the 2013 version of the
    Model Jury Instructions on Homicide should be followed.
    The defendant's final argument fails.     The judge erred by
    his use of the permissive words "may" and "should"4 when
    discussing use of excessive force in self-defense, rather than
    the clearly directive "must."       See Commonwealth v. Santos, 
    454 Mass. 770
    , 776-777 (2009).      See also Commonwealth v. McLaughlin,
    
    433 Mass. 558
    , 563 (2001) (where mandatory language is required,
    permissive language should not be used).       In Santos, a new trial
    was required because the judge used permissive language and
    "failed to make clear to the jury . . . that murder was
    unavailable," and not an option, where the killing occurred as a
    result of the use of excessive force in self-defense.       
    Id. at 776.
          Here, the judge instructed the jury that "[i]f the
    defendant used excessive force in defending himself in light of
    all the circumstances, the defendant may be found guilty of no
    more than manslaughter."      Unlike the judge at the underlying
    trial in Santos, the judge here made it abundantly clear that
    murder was not an option if the Commonwealth proved that the
    4
    See Commonwealth v. Caramanica, 
    49 Mass. App. Ct. 376
    , 378
    (2000) ("should" is permissive).
    24
    defendant used excessive force in lawfully defending himself.
    Although the judge did not use the precise language used in the
    Model Homicide Instructions (2013), at page 71, he anticipated
    the basic instruction that has been approved for current use.
    There is no merit to the defendant's claim that the judge
    incorrectly instructed the jury that voluntary manslaughter is
    the use of excessive force when lawfully defending oneself.
    This was a correct formulation.    As we said in Santos, "the use
    of excessive force deprives the defendant of his right to be
    acquitted altogether, entitling him instead to a verdict of
    manslaughter."    
    Santos, 454 Mass. at 775
    .    There was no error.
    6.     Review under G. L. c. 278, § 33E.    There was evidence
    that the victim was the first aggressor, that the victim
    introduced a knife during the fray, that the defendant was
    fearful of the victim, and that the defendant swung the knife
    wildly.    This evidence, particularly the evidence of the
    defendant's mental state, warranted an instruction on reasonable
    provocation.     The defendant was entitled to such an instruction,
    and it would have been compatible with excessive force in self-
    defense.    Indeed, it probably would have been more favorable to
    the defendant.    Such an instruction, had it been given, would
    have allowed the jury to find the defendant guilty of voluntary
    manslaughter if they had a reasonable doubt as to whether the
    victim initiated the fight by throwing the first punch.      Counsel
    25
    should have requested such an instruction, and such an
    instruction should have been given.    See Commonwealth v.
    Acevedo, 
    446 Mass. 435
    , 446-450 (2006).     The cumulative effect
    of the absence of this instruction and the errors in the
    prosecutor's closing argument create a substantial likelihood of
    a miscarriage of justice.    The judgment is vacated.
    The Commonwealth shall have the option of either retrying
    the defendant on the murder indictment or accepting a reduction
    of the verdict to manslaughter, which was the verdict urged by
    the defendant at his first trial, and which is the verdict he
    could best hope to obtain after a request for an instruction on
    reasonable provocation.     See Commonwealth v. Howard, 
    469 Mass. 721
    , 750 (2014).   The Commonwealth shall inform this court
    within fourteen days of the date this opinion issues whether it
    will retry the defendant for murder in the first degree or move
    to have the defendant sentenced for manslaughter.    After the
    Commonwealth so informs us, we will issue an appropriate
    rescript to the Superior Court.
    So ordered.
