He was a great artist. His brain is done for now. If you don't care about him, look at other musicians like Katy Perry recently and her video Bon (edit del: Bonus) Appetite - where she's treated like a meal. She then did a really messed up interview with a shrink where they were talking about her alter ego and she was crying.

This is a pattern, observe it across other public personalities. You don't have to like him/her.

These are no coincidences. These celebrities are likely cloned, or at the very least put through unknown (modern) MKULTRA procedures to change their thought patterns to the point where they turn into a vegetable.

Now apply that to your favorite musician. It will happen, all it takes is for them to step out of line and start speaking against their handlers, their handlers bosses, financiers etc.

Start caring because this shit is going to happen more often. It is like the curtain being pulled back and public figures are starting to realize what they've been put through to be controlled. More and more will speak out until audience members will question what's really going on.
