I think your all reading way to much in this. We dont know his motives. We can assume a lot of things to emphasize our own opinion, but we dont know the true, or whole, story.
What we do know, is he died, from an irresponsable act. We do know that he was "bragging" about his high tolerance, and typed the last words, "I told you I was hardcore". This is pure egotism, and that is what killed him. As far as the chat room goes, its irrelevent. They were his audience. He could have one found elsewhere.
MY opinion is that he killed himself by accident with his OWN stupidity.
