It's because his life and behavior were beyond bizarre over the years. And he was personally responsible for all of it. If the drug abuse allegations are true, it's likely he's directly responsible for his own death.
Well said, Dave. The key word is "responsible". Not everybody is a victim, and when they are, it doesn't mean you have a lifetime membership in the club. At some point, you have to get up, dust yourself off and "start with the man in the mirror" (pun intended). Every one of us has to endure some kind of hardship, every one of us struggles with something - but ultimately, every one of us is responsible for our actions.
