Pull the lever. 1. I'll save the people down the line from the anguish of having to choose. 2. I don't want to risk the next person pulling the lever for the wrong reasons. 3. If I don't pull the lever, I might be the person laying on the track when someone else pulls the lever. This is why I'm either (a) no good at, or (b) chaotic good at, RPGs.
Edit, typo
