So what was the final answer to the train ethics problem?

The one where you are at a junction for trains. One leads to five people tied down and the other one person tied down. In a run away train would you flip the switch to save five people by killing one? My answer Is to derail the train; or not to waste my time deciding and you should spend the last few seconds trying to figure out how to save everyone. Everyone is saved or bust. If it was a video game I would save five by killing one , but not in reality. I would hesitate and lose the chance to help.
