There is very little to be gained from a study of Anders Behring Breivik. He was a loner who was alienated from the society he lived in, suffered from depression, played violent video games, used steroids, listened to angry music and was of above average intelligence. This profile describes half the spree shooters in the last two decades, right down to the Columbine Massacre.
It is not Breivik's politics that make him significant. He was an outsider who despised society and escaped into romantic fantasies of omnipotence fed by video games and popular culture. Breivik cultivated a detached attitude toward the people around him and was obsessed with violent exercises of his masculinity. All this is common to killers of all political stripes and of no political affiliation whatsoever.
