This is a moral dilema I remember from when I was in school:
Its not very cheery, but its an ethical question that is sure to perplex some of us, while for others the decision is easy.
You are the gate keeper at a level crossing where the train tracks spilt in two just after the gate. There is a traffic jam and cars have blocked both tracks after they diverge and you can hear a train coming quickly in your direction.
The train is due to continue straight through the first level crossing, but this crossing is blocked by a mini bus with 10 people in it. The second crossing after the track splits is also blocked with a car with only one person in it. You have only 5 or 6 seconds to make a decision, you can either let the train pass on its route and hit the mini bus with ten people in it or you can flick the switch and divert the train onto the other track which has the car with only one person in it.
What do you do? Do you let fate decide and let the train pass on its destined route, killing all in the mini bus or do you take responsibility and switch the track killing the person in the car?
You dont have time to warn the occupants in the cars that a train is approaching around the bend.
Would you feel it was the right thing to do, sentencing the innocent person in the car to death when they are not in danger, or let fate take its course and not intervene yourself?
