The trolley problem, 100 pedos version

You are walking through a rail yard when you notice a runaway trolley for carrying explosive careening your way. Directly in its path are 100 pedophiles, bound and lying across the tracks. They will die if nothing is done.

There is a lever nearby. Pulling it will divert the trolley onto another track. On this other track, however, is a Nazi who cannot hear or see you or the trolley. You can stand by and do nothing, watching as 100 pedophiles die, or you can pull the lever, directly causing one Nazi’s death. Which is the more ethical choice?
