I definitely think one of his big issues was wanting to be scene as a symbol of wealth and status, and I vividly remember with each album how he'd move up the social ladder and hang around more and more afluent and 'out of touch' celebs, influencers, politicians, artsy folks that live in their own world, and wealthy people that want to use him as a tool for whatever their motivations are.
He always struck me as a guy that was excited (or maybe there's a better word) to kind of shed his original crowd that knew him before he blew up and get into those wealthy circles of people. Peep some of the Watch the Throne recording sessions where you got actors like Russel Crowe in the studio sessions instead of other rappers and producers.
Did you notice after the 2nd Grammy that he told Coodie that "Bono had some wine"? I remember when he started bragging that people like Bono from U2 and Chris Martin from Coldplay were willing to hang out with him.
It's like he always wants approval from people higher up the status ladder than himself. I think that's a big reason he was attracted to Kim more than just smashing.
