" The myth of pure evil, then, is surprisingly durable and elastic. Even when each side provokes and antagonizes the other, the myth can be invoked. Ironically, the myth fails to acknowledge mutual provocation, but it appears that both sides in a conflict are quite capable of seeing themselves as innocent victims and the other as unreasonably, gratuitously wicked.
