#1. Tricky. I would probably end up leaving it be, due to lack of commitment to either idea and just running out of time.
#2. Definately let the dude live again.
I think a reason why alot of people are okay with pulling the lever but not killing the waiting room person is because the man in the waiting room has a face, and the patients have likely already come to terms with their forthcoming death, whereas the train situation is just panic on all sides, no one is ready for it.
A little bit on a tangent here, but another moral question-ish.
Did anyone remember hearing about the beheading on a Greyhound bus in Canada earlier this year? It was pretty big news, and happened just outside of my city. I have to wonder how the other passengers on this bus didn't do anything to stop it. It really disgusts me.
If I was a passenger on that bus, and I saw something like that happening, I would have to try to stop it, there is no way I couldn't. I would rather die trying to save a life than life and have to deal with the fact that I could have saved a life but wussed out my entire life. What do other people think of that? Sacrificing yourself for a stranger?
