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.
