THERE IS A TOUCH of comedy in the tyrant’s rise to power, catastrophe though it is. The people he has pushed aside and trampled on are for the most part themselves compromised, cynical, or corrupt. Even if their fates are ghastly, it is satisfying to see them get their comeuppance, and as we watch the schemer bluster and connive and betray his way to the top, we are invited to take a kind of moral vacation.
