Smoking pot as a normal guy...should not be a issue. Smoking pot as someone diagnosed as paranoid schizophrenic....is a problem.
Agree, now, add smoking pot as a paranoid schizophrenic, who is focused on violence, whether in movies, books or video games, comes from a broken home, has serious anger issues and blames others for his self inflicted failures. There could be any number of other contributing factors, such as growing up without rational ownership of firearms in the house and being taught that they are an evil source of power. That can create a fascination in the mind of someone who has issues and feels powerless.
