There is a story told about a mother who came to Napoleon on behalf of her son, who was about to be executed. The mother asked the ruler to issue a pardon, but Napoleon pointed out that it was the man's second offense and justice demanded death.

"I don't ask for justice," the woman replied. "I plead for mercy."

The emperor objected, "But your son doesn't deserve mercy."

"Sir," the mother replied, "it would not be mercy if he deserved it, and mercy is all I ask."

Her son was granted the pardon.
