Let’s begin the discussion with a story.

Suppose you are a doctor in an emergency room and six patients come to you. They’ve been in a terrible trolley car wreck. Five of them sustained moderate injuries and one is severely injured. You could spend all day caring for the one severely injured victim, but in that time the five would die. Or you could look after the five, restore them to health, but during that time the one severely injured person would die.

I guess the majority would save the five and I assume the reason is simple: one life versus five.

Now this time you’re a transplant surgeon and you have five patients each in desperate need of an organ transplant in order to survive. One need a heart, one a lung, one a kidney, one a liver and the fifth a pancreas. And you have no organ donors. You are about to see them die and then it occurs to you. In the next room there’s a healthy guy who came in for a checkup. And he is taking a nap. You could go in very quietly yank out the five organs, that person would die. But you could save the five. Would you do it?  Please volunteer you reason with your answer.
