THE RUNAWAY TRAIN
An out-of-control train is heading down a rail track, ahead of which are five hikers unaware of the looming threat. On the bank where you’re standing is a switch that, if flicked, will send the trolley onto another track on which just one person is walking. There is no way to warn the hikers.
If you do nothing, five people die; flick the switch and just one person will die.
To make things worse, the five hikers are strangers - but the single person on the other track is a friend of yours.
What is the right thing to do?
It is proposed that you flick the switch to send the train to the track where the single person (your friend) is walking
