That's doing your best to save as many lives as you can without shooting anyone. It's not the same as murder.
if you believe the solution to the trolly problem is to actively change tracks
Nobody would kidnap a bunch of people and engineer that trolly scenario with "ethics experiments" goals in mind. It'd just be a game for his amusement/ego trip. It'd be just about sadism, regardless of how he justifies it. Such a person is going to continue to play with the survivors until he tortures and rapes the last one to death. Everyone in the tracks and the person at the button is going to die. The solution to any actual trolly problem that could exist in real life is not to engage with the sadism of whoever put everyone in that situation by playing along. Every death will be on the lunatic, not you.
