"Nietzsche despised the politics of rancour, not because rancour cannot be justified but because, no matter where it comes from, rancour is bad for the soul. That’s what The White Ribbon is about, revolt poisoned by rancour. At one point Klara kills a pet parakeet with her father’s scissors and leaves it on his desk: evil authority breeds evil in its rebel offspring. These children aren’t just imitating their parents, beating as they are beaten, which would mean more of the same: they are subversives fighting the bad with the bad and portending worse."
