Maybe this question was asked before, but I didn't see such topic; so:
Imagine that you were sent on a mission. You have 24 hours to kill your best friend while talking with him/her, by shooting him/her in his/her chest. He/she would know you did that, and wouldn't know, why. (You can't tell him/her about that)
If you don't do that, 10 innocent people you don't know will die (for example, a small air plane will be blown up).
No matter what you chose, you can't ever tell anyone about what you've done and why, or both 10 innocent people and your best friend will be killed.
What would you choose: Let your friend live, and have the burden of killing 10 innocent people you didn't even know, or kill your friend and save 10 other lives, who don't know about that and won't even thank you for that?
