I read that article the other day @Critical Thinker, and this guy clearly follows one specific conspiracy thinker stereotype. A mixture of social misfit, bad self-esteem and grim perception of the future. As I understand from the article, the guy is a white supremacist, but the big question is always which of all of these comes first. As pointed out in the article: It is certainly possible for an individual to learn and accept conspiracy theories as truth, loose hope for the future, and alienate his or herself from society, friends and family. But I believe the process almost always originates with low self-esteem, and the ego kick of "knowing the truth" and become "special" is appeals to these individuals. But most of these believers will feel frustrated when "no one gets it". They'll struggle to convince others. When they fail, they feel rejected and will subsequently isolate themselves. The isolation becomes a problem, because it limits the individual's exposure to deviating ideas, contributing to further isolation. It becomes like a sect. The problem then comes from the fact that the perceived problem doesn't actually exist. Delusions don't have solutions. So the individual will feel frustrated when there no solution is in sight. This produces stress, which together with a lost hope might cause a mental breakdown in the end. This brings suicidal thoughts, and irrational anger. But I think it takes a life-long feeling of worthlessness and failure to push someone to kill completely innocent people, especially children. I think that kind of dark fantasies are created as a way for such individuals to make a name for themselves in the end. In their world conventional suicide would be the the ultimate proof of failure, so this kind of mad killing spree is one last desperate effort to become remembered. And to get revenge on society.
