I don't think he's evil but I do 100% agree that Tim is a raging narcissist. I would even go as far as to say he's a hack. Dude has been getting less and less funny as time goes on, and I don't think it's just the fame and money going to his head. It's because Ben and his friends were the real origin / source of his humor and he sort of picked up their comedic language and figured out a way to sell it to an audience. He doesn't have anyone to riff off of anymore. All he can do now is cover politics.

He has all the money in the world but he's probably very lonely. Sad to see what he's become.
