ENFP: extreme paranoia to the point of hurting others physically, emotionally and legally (even if they didn't mean too, after their episode was over) I found this odd, (because normally they're the opposite of paranoid, they are typically some of the most optomistic folks I tend to meet).
ex: Hitler, Jim Jones, Manson, David Koresh, most cult Leaders.
ENTJ: Hyperaggresive, they're always right attitude, inablity to see or admit their own weaknesses. Sadistic pleasure in berating others. This can also go over to sadistic tendencies in bed.
ex: Probably Hitler's best generals and advisors that actually pulled off his crazy schemes
ESFP: fake compulsive liars who actually does like people but are so selfish and unaware of how their actions effect others, they end up fucking over people anyways (even if that wasn't their intent).
ex: the most annoying bratty, superficial child one can imagine.

The above are the only examples that I've personally known in life (and only the ones gone bad, I know ESFPs who are bright and who's company I enjoy).
I'm very interested to hear others' personal experiences of types gone bad, not just had bad form in that particular intance, but completely off their rocker, gone bad. There are a lot others, I'm 90% I'm right on, that are famous or historical characters but I don't know them personally, so I'll refrain, for this thread.
I know any type can go bad, but the only one I have trouble imagining is the INFJ. I could see them killing themselves, but not hurting others. When I think of go bad, I take it as first and foremost fucking over other people. They probably do exist, but that is the only, I can't picture.
Quenk has a book about what specific types will do when they are stressed but that's different, since normal healthy individuals can exhibit those traits. I took "gone bad", to mean bordeline sociapathic/schizoid/fill in the blank, need to call in a pyschiatrist for serious help, gone bad.
