Hi @jadams2k18

First, whatever the replies; most people will NOT act- simply out of the fear of becoming tainted with death.
Second, the question about actually killing someone to avoid a worse fate misses one point- there is no right choice. Both ways you are a loser- either a coward and indecisive person OR a heartless amoral being.
Third, how much ever we try to 'induce' the atmosphere of pressure and tension- it cannot be duplicated. Let me explain: If I say a bullet hit my arm, breaking a lot of bone and tissue- This explanation of what happened cannot even come close to the ACTUAL experience. The violence and pain cannot be conveyed, imagined at most but never really conveyed. The point: If I cannot duplicate conditions, the results are unreliable at best.

PS: Blow up the train!!!
