Has anyone actually researched Harold Camping?

I have been for about a week and I came across something interesting. His Wikipedia page says he left the Church he was involved with and othe sites say he was removed. This was in 1988 mind you. Now everything Ive studied on him states that he said no one between 1988 and 1994 could be saved (1994 being his first prediction date) Now to me it seems that our pal H. Camping got mad at his Church for some reason so he decided to say that all Churches are evil since 1988. Anyone else think that he is just harboring hate for organized religion?
