"To be wronged is nothing," said Confucius — "unless you continue to remember it."
Forgetting is not forgiving. Forgiveness is Christianity's noblest quality. As Martin Luther King Jr. said, "Hate cannot drive out hate; only love can do that."
Not everyone is Christian. Revenge, too, has its appeal. It defeats death itself, says Japan's 18th-century samurai classic "Hagakure": "With martial valor, if one becomes like a revengeful ghost and shows great determination, though his head is cut off, he should not die."
