Oh and
” I can ask you a million what ifs.”
Bring them on, though try to keep them on subject
” What if you were forced to let die either your boss or your neighbor, who would you let die?”
Dont see how that is relevant. This feeds back to the discussion on limited resources which as indicated there are hard to resolve. On theoretical level, as to your question though, assuming all things were equal (the odds of saving them, there expected recovery, who is closer, who got sick first, Whose a bigger talmid chacham, who i like better etc etc etc) Id probably flip a coin.
Why do you ask?
