It is a thought experiment in ethics, which there are five people tied up and unable to move on the railway. Then, the runaway trolley was moving down to the railway tracks and headed straight to those people. If you were in that situation, you would be able to pull the lever, so the trolley will switch to a different set of tracks. However, you notice that there is one person on the sidetrack; this means that you will be killing him instead. This is a very difficult decision to make, as you could either or nothing, and the trolley kills the five people on the main track or pulls the lever, so the trolley onto the side track where it will kill one
