When you get punched in the mouth, what’s your natural reaction? Punch back. When you get embarrassed by someone, what do you want to do? Embarrass them back. And when someone defeats you, what do you hope to do in return? Beat them right back – and do them badly. So goes the cycle of human emotions. Revenge, no matter how solid our hearts are, how true our spirit is or how balanced our head sits on our shoulders, is a part of our basic instincts.
