The tyrant's misery

The tyrant becomes and, is of necessity, more jealous, more faithless, more unjust, more friendless, more impious, than he was at first. He is the purveyor, and cherisher, of every sort of vice, and the consequence, is that he is supremely miserable, and that he makes everybody else, as miserable as himself. Plato. The Republic. Book 8.
