" Many writers have dreamed up republics and kingdoms that bear no resemblance to experience and never existed in reality; there is such a gap between how people actually live and how they ought to live that anyone who declines to behave as people do, in order to behave as they should, is schooling himself for catastrophe and had better forget personal security: if you always want to play the good man in a world where most people are not good, you’ll end up badly. Hence, if a ruler wants to survive, he’ll have to learn to stop being good, at least when the occasion demands. "
― Niccolò Machiavelli , The Prince
