Mental illness surely is a factor, but I don't think it's what pushes people over the edge. Remembering my teenage years, the times I acted badly were because of anger. Extreme frustration towards a society or people who I felt treated me unfairly. The hardest to deal with was (perceived) hypocrisy from people who were in a position of power. Looking at US media, politics and justice is infuriating as an outsider. Everything that's done under guise of "freedom" and "democracy". All the "morality" work from people who by their own standard would go straight to hell. Zero accountability for anything. Trickling down might not work for money, it surely does for the poison that this system produces. At least in openly totalitarian countries, people get a chance to see their government for what it is.
