May include behaviour that is adaptive or rational. Eg. Looting after disasters. Some criminal
behaviour is adaptive. Eg. Selling drugs can be a way to make money, in a bad situation.

-Mentally Ill people are more likely to be violent compared to healthy general public.
-Aperson who perceives a threat to their personal integrity will act in self defence
-violence is a way of neutralizing a perceived threat
-Threat delusions cause a person to believe they are being persecuted
-Men are more likely to aggress than women.
