A moral quandary is a problem in which you have to make a difficult decision in which nothing stands out as the "right" answer.
I love these. I despise movies that have characters that are just evil for the sake of being evil. I like decisions that are morally grey, and difficult. Black and white decisions are just a test of personality.
Answer these, and post your own:
You are legally immune in all these situations, and people will agree with whatever you do.
You can bring peace on Earth, and make all men happy, excluding yourself. In order to do this, you have to torture and kill a young girl.
Do you do it? You could save millions of lives by ending violence.
Edit: It will not prevent you from being happy, it will just not force you into happiness.
A madman has planted bombs all over New York city. He has been captured, but will not reveal where he has placed the bomb. He has a rare condition so he does not feel pain, and the only way to get the locations of the bombs is to torture his (innocent) wife.
Do you do it? You could save thousands of lives, and nobody would die.
A small train is coming down a track. 5 people are tied to it, and will be killed by the train. You are on a bridge with a large burly man, and his body could stop the train, saving the 5 people. Do you push him off the bridge, to stop the train? You could save 5 people, at the cost of 1.
