A lot of child stars had their childhood ripped away from them, but they didn't have sleepovers with a bunch of 12 year olds. What happened with his childhood is terrible, but there's the right way to deal with it and the wrong way, he did it the wrong way.
I understand where your coming from, and it's important to remember that you don't have to be a childhood star to have your childhood ripped away from you. And having a bad childhood does not justify adult decisions. It may influence them, but not justify.
It's all by the by and probably not the best time to argue these past events, but just reflect on his passing and those family he leaves behind.
