Hm, by the way: “psycopathy” trait is not about psycopathy at all: absence of guilt by itself is not enough to diagnose psycopathy and it does not turns someone into some kind of omnicidal maniac. For such person to be diagnosed with psycopathy weak control over urges must also be present. And without such weakness (or even more so - with trait like “addiction resistant”) survivor would be more like schizoid rather than psychopath.
