A bit unrealistic but I always wonder what I'd be thinking about if I were in that kind if situation. Hopefully not for killing anybody, mind you. I think it would probably be: "well, at least it'll be over soon." In the grand scheme of things, 20 minutes is nothing compared to the way people did things a long time ago. This isn't a statement for or against the death penalty, just an observation and a thought experiment. I'm against the DP generally.
