Trying not to sound too cold, he seemed like a very nice guy and i did not know him. It was not surprising for me. I remember seeing interview with him when he took things very personal and could not let things go some year back. Thought at that time that he was at high risk of suicide. He seemed to have a self loathing personality / depression and obsessive behaviors.

Staying on the Internet and be dependent on it in some way financially working as a streamer with all the short form communication and negativity online. Together with cyber bullies etc. A lot of things creating a perfect storm for what seemed to be a sensitive and very nice guy. Easy to say that his family and real life friends should have seen it too and make him change path but in reality it is difficult. Especially since things that make it worse like sitting down and playing chess all day / night and not getting enough sleep, together with cyber bullies is also the things that you love, you earn money on and you have many of your friends there.
