I never came across anyone in whom the moral sense was dominant who was not heartless, cruel, vindictive, log-stupid, and entirely lacking in the smallest sense of humanity. Moral people, as they are termed, are simple beasts.
People may fail many times, but they become failures only when they begin to blame someone else. Always forgive your enemies; nothing annoys them so much.
Selfishness is not living as one wishes to live; it is asking others to live as one wishes to live. And unselfishness is letting other people's lives alone, not interfering with them. Selfishness always aims at uniformity of type. Unselfishness recognizes infinite variety of type as a delightful thing, accepts it, acquiesces in it, enjoys it.
