Moral Dilemna

What do you do when you're stuck between obligation to two different people. On one hand, you do what you're supposed to do and 50 people aren't made slightly worse off, but you have to turn in a good friend. On the otherhand, if you do nothing everyone else gets stuck dealing with the ramifications of your friend's actions.

I know what the right thing to do is, but it doesn't make it easy or enjoyable.
