There is a legend told of a mother who sought from Napoleon the pardon of her son. The emperor said it was the man’s second offense, and justice demanded his death. “I don’t ask for justice,” said the mother. “I plead for mercy.”

“But,” said the emperor, “he does not deserve mercy.”

“Sir,” cried the mother, “it would not be mercy if he deserved it, and mercy is all I ask.”

“Well, then,” said the emperor, “I will show mercy.” And her son was saved.
