right and wrong

[Reincarnate]

Let's talk examples instead so you may be able to better explain yourself. I'll use one from the video.

You are a doctor. You've got five patients about to die if they don't get organ transplants immediately. In the next room, you see Chuck, a man who is perfectly healthy. You could let the five patients die, or you could kill Chuck and use his organs to save the five patients.

What would you do, and why is this moral call right/wrong, and why is it objective?
