disregarding the afterlife version, plenty of psychotics and schizophrenics would probably beg to differ
Heh, the whole phenomenon of "personal hell" apparently doesn't exist either.
They're like racism consultants..
Or psychiatry and the peddlers therein?
Hell was invented by lunatics and propagated by scam artists, err "churches", to pick your pocket clean and enforce their social order.
In the beginning of Christianity? I'm afraid history disagrees as the founders of that religion most probably had a legitimate belief in their organization. As is a prime example in the amount of splinter factions of Christianity and Islam, the real lunatics came out when the issue of interpretation reared its head.
