Malachi is playing baseball when the umpire calls a strike.He explodes, starts screaming at the umpire, and threatens to hit him with the bat.He appears to be "out of control" because of his anger.This is typical of Malachi's aggressive reactions to frustration and stress.He may well meet the DSM-5 diagnostic criteria for:

A) conduct disorder.
B) oppositional defiant disorder.
C) antisocial personality disorder.
D) intermittent explosive disorder.

Malachi's explosive anger and aggression in response to frustration and stress suggest the possibility of intermittent explosive disorder, which is characterized by recurrent behavioral outbursts involving a failure to control aggressive impulses. While conduct disorder and oppositional defiant disorder also involve disobedience and aggressive behavior, they typically present with a more chronic pattern of such behaviors and are often evident earlier in childhood. Antisocial personality disorder involves a pervasive disregard for the rights of others, and while Malachi's behavior is concerning, there is not enough information to suggest a diagnosis at this time.
