Reading his book explains a lot. He's admittedly a people pleaser. He cares a lot about what people think of him.
He went from being one of the coolest people in the history of Hollywood, to his wife fukking around on him and more or less still lusting for Pac, his kids wanting Pac to be their dad and emancipated. And all of this is public knowledge.
It's fueling it's own fire at this point in that, the more the public knows, the more he is trying to smooth it over and he's saying dumber and dumber shyt and doing dumber and dumber shyt. It's a vicious cycle. He has to break though. I don't know what that looks like. I have some ideas...but he has to break the cycle himself.
EDIT: This is from the book...clearly I'm not that far along yet.
