Suicide is obviously a very sensitive topic in this community and to the world. Do i think it's ok to just kill yourself? No, but sadly everyone has their breaking points, and Chester Bennington obviously reached his point. I'm sure the thoughts of family, friends, future and everything else went through his mind before his act. But he obviously thought that the world could go on without him. Will people be sad that he is gone? Yea of course, it's natural to miss someone.
What Chester did was a permanent solution to a temporary problem. I don't want to be that guy who becomes a dick for his thoughts on suicide, but agree with me or not, my thoughts have been shared.
Basically yes, though I'm not sure it's that simple, I respect your opinion though, while vague thoughts like that likely crossed his mind, mental health issues warp your frame of mind, it makes some kinds of thoughts like sound cannons, and some other ones seem like whispers, if chester where to have looked at this logically, he would have known that he was a champion for millions of people with mental health issues, it's not just his family he left behind, its his entire fan base whom many of them he helped or was helping through very difficult times, those peoples champion has fallen, as always we must do everything possible to prevent others from falling as well.
Imagine you're one of his fans who is suicidal, listens to his music religiously, they're probably thinking "if chester can't win this, how can I?" they see his money, his fame, his passion, and his struggles, and they have seen him take the final fall now, this could have a devastating impact on many many people.
I'm not saying this to criticize you, just to give my opinion, and to once again point out that depressive mind states almost always lack logic, just because he thought "the world will go on without me" doesn't mean he was right, I hate to say this but its entirely possible this will worsen a lot of peoples already severe depression, and more than one persons world might literally not go on without him, this guy was a champion of this stuff, it's not a good look to say the least.
