You can't really boil down trolley problems into "Would you kill x or y?".

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.
