Dani Rodrik in Saif el Qaddafi and Me
The conundrum that advisers to authoritarian regimes face is akin to a long-standing problem in moral philosophy known as the dilemma of “dirty hands.” A terrorist is holding several people hostage, and he asks you to deliver water and food to them. You may choose the moral high ground and say, “I will never deal with a terrorist.” But you will have passed up an opportunity to assist the hostages. Most moral philosophers would say that helping the hostages is the right thing to do in this instance, even if doing so also helps the terrorist.
But choosing an action for the greater good does not absolve us from moral culpability. Our hands do become dirty when we help a terrorist or a dictator. The philosopher Michael Walzer puts it well: “It is easy to get one’s hands dirty in politics.” He immediately adds, however, that this getting one’s hands dirty in this way is “often the right thing to do.”
