Violence comes in two flavors: planned violence inflicted for a purpose, and spontaneous violence set off by passion. Violence for a purpose, designed to get something the perpetrator desires, might be as prosaic as mugging someone on the street, or as earth-shattering as launching a global war. The emphasis in each case is on effective strategy, planned in advance, sometimes in excruciating detail, and always aimed at gaining resources or control. This is dopamine-driven aggression, and it tends to have a low emotional content. It is cold violence.
