> You can't really boil down trolley problems into "Would you kill x or y?".
Thoughts on why you can't? I think you can and must.
It's a big difference that someone is already in the way. If you take no action they die anyway. If you suddenly collapse on the ground or get struck by lightning before you can pull the lever, they still die. It's not your fault that they died.
Generally someone is already in the way of the trolley, so the question is more like "Would you kill x in order to save y?".
So you could ask people this:
Would you kill a baby to save 5 elderly people?
Would you kill 5 elderly people to save a baby?
How people answer these questions does not really have anything to do with abortion.
