Where there is no truly right answer: Just different, painful consequences. Take for example, this classic scenario. A train is hurdling down the tracks. Your friend is tied down on the right track, and ten strangers are tied down on the left track. You can only change which track the train is going down: What do you choose to do, and why? Note: Choosing not to choose still results in someone dying. You just chose to abdicate the responsibility. Just to clarify that.
