Retaliation is an act of revenge. Before you initiate retaliation on someone who has wronged you, consider whether he or she might have a ninja alter ego and a set of nunchucks stashed away.
The noun retaliation stems from the Latin retaliare, meaning “pay back in kind.” Notice the word kind in that definition. Retaliation used to have both good and evil connotations. Now, though, it’s important to read that kind as synonymous with type or sort because retaliation has since lost its positive sense. Martin Luther King, Jr. once said, “Man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.”
