How do you know?
Aaron had been talking about suicide years before this, maybe we should just blame reddit?
Edit: Why the downvotes? Fact is that we don't know why Aaron killed himself, but we do know that he had a prior history of depression and in 2007 posted what seemed very much like a suicide note.
Frankly, making claims like "If x had (not) done y he'd still be alive" and presenting them as facts is straight up disgusting.
