idk what to say - if one of your great-great-great-great-great grandpappys was a psychopath, but nobody else in your bloodline was, does that make you a psychopath? especially, consider the case of rape, evil ones rape. raped women have babies. the women sometimes escape, and the child is not raised in the presence of the psychopaths.

having relatives who are psychopathic doesn't make you psychopathic. psychopathy is an acquired syndrome, and it's the central feature of what the whole long story arc of the last 12000 years since the great flood (meteorite strikes) are about.

there's a lot more to the story but that's the essential insight i want to address in your horror that you might be descended from a demon somewhere way back.
