Children who grow up to be psychos are rare.
Not being sarcastic but am I taking this out of context? I think that most adults that grow up severely depressed and suicidal/homicidal most of the negative impetus for these feelings stem from something bad that happened during childhood.
And dude,I took like two psych classes towards my CJ degree so I'm not going to debate psychosis with you (I'd lose). What I will say is that I have a wealth of experience dealing with people in bad life situations, and not all but I'd hypothesis that the majority have their anti social issues stemming from what happened to them as kids, i.e. parents were drunks/drug abusers, parents were rich but tuned out, didn't notice their little spoiled brat turning into "Nero", the traumatic effect bullies are having on kids that aren't in the "in" crowds, and a biggie is the extreme prevalence of sexual abuse of both boys and girls.
what I've noticed is that at a minimum it turns boys into men with extreme sexual identity/depression issues, and girls into hyper promiscuous/depressives. feel free to school me if I'm wrong.
