It's slightly frustrating how mental illness is portrayed after mass shootings. It seems the general consensus the public and media have come to is to put the blame there. It all seems pretty absurd. For all we know, his decisions were perfectly within whatever belief system he had constructed for himself, just the same as any terrorist, which rightfully has been pointed out many times already is not automatically classified as mental illness. Ever consider this kid was just a bullied, disgruntled loser who externalized all his problems and saw no other way to get back at society? Maybe he just wanted to be famous, and this was his only option. That sounds pathetic and wicked, but, aside from maybe some pathological personality traits, is not mental illness. For all you know, he could be an anti-gun liberal who, after seeing the other two recent mass shootings, wanted to make a statement against firearms by releasing a few rounds. He could have had any number of motives that have nothing to do with mental illness.
