I have a close friend who has been dating this girl for about six years now. He has cheated on her in the past, and she has found out, remained in the relationship with him. Recently, I have found out he's doing it yet again, and she's ignorant of it. Worst of all, he's cheating on a girl who sells her body on the side. His girlfriend and I are close. I regard her as a best friend. Now, I know breaking the guy code here is wrong. I have known him since childhood. But still, she's a friend of mine who I care for immensely.

If your friend plans to rob the bank/rape a girl, what would you do?
Obviously, 1. Stop him from doing that, by persuasion
2. If that doesn't work, what then? Do you call the police and betray him?
The trick here is the word betray; meaning dishonesty, doing things behind someone's back. There is only one way here --- be honest. Tell your friend, "Lest you think I betray you behind your back. I am telling you right now, I am going to call the police if you insist on doing XYZ. I am willing to sacrifice our friendship. Anyway, why would I befriend a robber/rapist?" In other words, what is there to lose?
