Well ... to be fair, people are going to describe his death according to their perspectives, aren't they? It's not likely he's going to slip in a last-minute 'oh, and btw, I'm a Satanist' bit, is it?
I would love to know if he really was devout and lovely or if there was something else going on. I agree the incest must be nonsense - didn't someone prove that he wasn't even anywhere near here at the cited dates? I forget.
