A runaway trolley is heading down the tracks toward five workers who will be killed if the trolley continues on this course. You're walking on a bridge that hangs over the tracks, in between the trolley and the five workers. Next to you on the bridge is a stranger who happens to be very large. If you do nothing the trolley will kill the five workers. The only way to save the lives of these workers is to push the stranger off and onto the tracks below, where their large body will stop the trolley, causing their death. Push the stranger off or let the workers die?
