An article at Wired takes a look at two multiplayer survival games, DayZ and Rust, and at the behavior of players when their actions are freed from a civilized moral code. 'Violence wouldn't bother a psychopath, [Dr. Adam Perkins] says, but they might have another incentive to avoid violence: the consequences of getting caught. Most psychopaths are logical people, he says, and understand that actions bring consequences. The threat of repercussions — say, for example, prison — might keep them from acting out. Such disincentives do not exist in virtual worlds. Absent a sense of empathy, you're free to rob and kill at will.
