Spreading the Misery Around

Moreover, as we were saying before, [the tyrant] grows worse from having power:

he 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.


-- Socrates, Republic of Plato, Book IX
