I believe him. He goes into much more detail about the incident in his autobiography, if you want to know more than a few sound bites.
As for whether I "like" him - I don't know him personally. Based on his interviews, I don't think he's someone I'd want to sit and have a few beers with. That doesn't make him a bad person, just not someone I'd be comfortable conversing with.
I find his music to be nothing short of brilliant. His lyrics are relatable to me (although I'm not as F'd up as the characters in his songs) and the music ranks right up there with the best classical compositions. I don't believe in reincarnation, but if I did, I'd think he was Beethoven in a previous life.
