" The psychological analysis of any normal development will make it clear that, if he is to grow up, it is not merely unavoidable but actually essential that the individual should do and assimilate a certain amount of evil, and that he should be able to overcome the conflicts involved in this process. The achievement of independence involves the capacity of the ego not only to adopt the values of the collective but often also to secure the fulfilment of those needs of the individual which run counter to collective values – and this entails doing evil. "
