It's that thing 'this guy made a lot of money, he's smart and done everything right in life' that makes my piss boil.

He actually thinks he's sort of a prophet so he kind of believes his own mythology.
And much as I liked his music, it seems that he's going through a very unusual public whirlpool of mental health issues. He sees himself as a prophet. So that's close to delusion, surely? I don't think that's a reflection on his intellect or his musical ability. But it's definitely a reflection of his mental state over the past few years.
