The sadist doesn't create a masochist; he finds him readymade

"Do we wonder why one of man's chief characteristics is his tortured dissatisfaction with himself, his constant self-criticism? It is the only way he has to overcome the sense of hopeless limitation inherent in his real situation. Dictators, revivalists, and sadists know that people like to be lashed with accusations of their own basic unworthiness because it reflects how they truly feel about themselves. The sadist doesn't create a masochist; he finds him readymade. Thus people are offered one way of overcoming unworthiness: the chance to idealize the self, to lift it onto truly heroic levels. In this way man sets up the complementary dialogue with himself that is natural to his condition. He criticizes himself because he falls short of the heroic ideals he needs to meet in order to be a really imposing creation."
