Option 1: Let the serial killer-rapist go free. You know they will continue harming others, but you do not take any life yourself.
Option 2: Execute a 100% innocent man in public. The man is certainly innocent, and your action will end an innocent life for no reason other than this choice.
Which do you choose and why?
In option 2, is it clear that’s what’s happening to everyone, or am I framing this guy? I guess it doesn’t really change the trolley problem logic, but that would feel a lot worse.
