The trolley problem and the presidential election: There is a thought experiment in moral philosophy, made famous by Philippa Foot, called the trolley problem. Imagine you are the driver of a runaway trolley that you can steer but not stop. Up ahead, are five workers you are heading to kill. On the right side track, is one worker on the tracks, that you would kill. What do you choose? The lesser evil? But one cannot choose evil for a good. That's the problem.
