Agreed re actively making a decision: my answer was mostly not to pull the lever, and if I analyse my feelings it's because then the results aren't my fault. Pulling the lever makes me party to the situation.

Disagree re realism though. You never get a chance to think in real life; and any situation in which you could deliberate what the moral course of action is, is a situation you could avoid entirely. Really the closest to trolly problems in real life are public policy decisions - which are real and affect all of us. So yes I guess I've argued myself around to agreeing again :).
