I've read over the last few months about how aggressive he's been acting towards fans on his Twitter page, threatening to beat them up for liking the band's old stuff more than their newer. I think he's been in a dark place mentally for a while now. It's a damn shame when depression gets this bad, and I understand the whole "he had kids, how could he do this to them?" aspect of this; something that most normal feel when hearing news about a parent committing suicide...but at the same time, very deep depression plays tricks with your mind. I'm sure in his head he felt this would be better for his kids and everyone else. Trying to rid yourself of crippling depression and the thoughts it brings is like trying to will yourself to be healed of a broken leg or a physical illness, it's just not going to happen.
