Just because I stopped the trolley, doesn’t mean I’m going to untie them.

Not doing so would lead to events that you talk with their families

Pull the lever and run away

Just pull the lever, and walk away.
You saved their lives, but they can’t shake hands when they’re still tied up.

I mean, I don’t think there’d be a lot of small talk. It’d be more like “thank you thank you, now let’s call the police”

And by the time you finish untying everybody, the cops’ll be there and then you get to be questioned! What fun!

To bad they are all going to die.
