Corruption

Corruption is one of the worst failures in a politician. I was going to say, the worst, but among all possible failings, fanaticism must reign supreme. A corrupt man may yet retain scruples restraining him from greater evil, but a fanatic cares only for one ideal, and believes the end justifies the means, which is the belief at the heart of evil. In Iran, the Supreme Leader seems to embody both flaws, corruption and fanaticism, which is why his reign has been drenched in blood.
