I will use an extreme example, although Dr. Lambert might think this is unfair. Let us consider the example of gangland violence where somebody uses violence against another person in a different gang. I would have thought that the reason for that is that the person perpetrating the violence adopts a rational decision that their problems can be resolved by inflicting violence on this other person and it is not really that they are under stress.
