" Lo, lo,” said Lady Prudence, “how easily is every man inclined to his own desire and to his own pleasure. Surely, the words of the Physicians should not be understood in this way. For certain, wickedness is not the contrary of wickedness, nor vengeance the contrary of vengeance, nor wrong the contrary of wrong, for, in fact, they are the same. And, therefore, one vengeance is not cured by another vengeance, nor one wrong by another wrong, but each one of them increases and aggravates the other. "

― Geoffrey Chaucer , The Canterbury Tales
