Jim Jones’s son says the opposite—he maintains that his father knew he was a fraud every day of his life, and the psychological torment of that knowledge was one factor that led to the taking of his own life, and taking his 900+ followers with him (1/3 of whom were innocent babies and children; so sad).
Good point - I think it can go either way with these things. I was watching the obama-rama last night and kind of thought that he was believing all that crap but then again what do I know :)
