you come across a fork in train tracks. on the path that the train is currently set to follow is a group of thirty kids that are tied to the tracks (i dunno what kind of sadistic person would take so much time to do that, but i guess it's possible). on the other fork there are two kids tied to the tracks. you have two options, let the train follow its course and run over thirty kids, or pull the lever to change the course and the train will run over two kids as opposed to thirty. what would you do?
