I always think that one of the purposes of this type of attack is to show – or to galvanize – the moral bankruptcy of the regime and the society. To show that when it is provoked it will lash out with cruel, disproportionate, insane violence; to show that it is not a legitimate or safe place for marginalized groups by provoking violence on the bodies of the marginalized. If we lived in a better world, or even in Norway, people would respond by refusing to lash out, by acting with magnanimity and greatness. But all that ever happens is that we see that both the terrorists and the regime are violent and morally bankrupt.

It’s an epistemological crime, it’s intended to produce despair. Mass killings like this are the non-stae mirror of the prison camp, because they’re intended to break down people’s ordinary humanity.
