'Man is evil'—all the wisest men have told me that to comfort me. Oh, if only this were true today! For evil is man's strength. "Man must become better and more evil"—this is what I teach. The greatest evil is necessary for the superman's greatest achievement. Perhaps it was good the poor people's sage took upon himself and suffered the sins of humanity. I, on the other hand, rejoice in great sins as my consolation. —Thus Spake Zarathustra, IV, Of the Higher Man, 5.
