you are a trolley, and this man is going to kill the people tied to the tracks
you can save their lives if you pull the lever, which will have the shooter instead kill your wife, who is also a trolley
now that is the expression of a trolley caught in a terrible ethical dilemma
Not really. The trolley-wife is a bigger moral agent than five humans put together so the choice you want to make is also the choice you should make. No dilemma at all.
