Cut off a toe
Imagine you are standing beside some tram tracks. In the distance, you spot a runaway trolley hurtling down the tracks towards five workers who cannot hear it coming. Even if they do spot it, they won’t be able to move out of the way in time.
As this disaster looms, you glance down and see a lever connected to the tracks. You realise that if you pull the lever, the tram will be diverted down a second set of tracks away from the five unsuspecting workers.
However, down this side track is one lone worker, just as oblivious as his colleagues.
So, would you; pull the lever, leading to one death saving five or let fate happen and result in the death of five?
