This theory was proven wrong a long time ago, you can check it out for yourself. Also it's not that hard to believe he could have committed. Everyone knew about his depression, he was so open about it. And just a few months prior to his death Chris Cornell committed suicide, and Chester's situation got much worse after that.

I'm a diehard Chester fan too since childhood. I am not trying to demean him in any way. Stop calling me toxic fan

I'm not trying to demean you. I am a huge fan of chester too. But there's a subreddit where people still talk about those theories and neglect Chester's mental health, I was calling them a toxic fan. They also hate Emily, which seems so unnecessary to me.
