Classic Trolley Problem

Divert a runaway trolley to kill one instead of five.

Scenario

A runaway trolley is hurtling down a track toward five people who are tied to the track and will be killed if it continues. You are standing next to a switch. If you pull the switch, the trolley will divert onto a side track, where it will kill one person who is tied to that track instead. You did not put any of these people on the tracks; you have no other options.

Question

Will you pull the switch?
