 If he had enough mental problems, enough issues going on in his life, it could simply be this situation right here. I've been picked on and bullied my entire life. Tried to join the shooting team. I'm still obsessed with guns. I have a shirt from a YouTube channel that's all about shooting. So I'm obsessed with shooting or at least very interested with shooting. Those a-holes didn't let me on the shooting team and everyone was so mean to me throughout my life. I have no friends.
