Actually, I couldn't decide either. I tried but all I could
   think of is that WHOEVER came up with this awful choice forced
   upon me should go to prison. [not you* but whatever wicked
   person made me choose like this] But I have a "thing" about
   thought experiments that are unrealistic. Reasoning makes sense
   but it's an unconvincing argument for me because that kind of
   choice just doesn't happen in real life.
