I've always thought about this as horrible as it sounds. I find there are rarely instances of truly great artists that didn't have some f*cked up shit happen to them at some point. Looking at it objectively that kind of stuff will always give people material to write about and people can empathise with certain people's struggles and it makes them enjoy it more. Michael Jackson, Brian Wilson, Marvin Gaye and so many more were beaten by their fathers (Gaye eventually murdered by his). Eminem was abandoned by his father, had his Munchhausen-by-proxy mother and f*cked up wife. 50 Cent's mother was murdered and he also got shot. Kendrick and loads of other rappers grew up in poverty and violence. Anthony Kiedis, Jim Morrison, etc.. were on hard drugs. One of the reasons Eminem fell off was because he became rich and a lot of his problems went away, he doesn't have anything to sing about anymore except for how people say he's finished. A lot of them died young or before their time as well. I remember a tweet where someone jokingly wrote something like "How do I make sure I give myself just enough childhood trauma that they'll turn out funny". Which kinda rings true. So does childhood trauma help create a genius? If everyone had great parents and upbringings would we have less genuinely great music/books/film?
