I read the same story and that was a pretty vindictive thing to do and what a psycho. Who knows what he did besides break up with her, but I don't know if it warranted that. It could have been worse, he could have been with Lorraina Bobbit .
As far as revenge goes for me, I'm no passivist but I think seeking revenge can hurt me more then the intended victim. The negativity and hate hurt you more then you think and if you feed into it can literally make you sick. It's like taking poison and expecting the other person to die. That being said I'm human and if I'm wronged all that spiritual shit could go out the window and I'm going to be seeking my pound of flesh.
Revenge role play could be interesting. An asshole boss getting his just do, or the armed robber looking to stick up the docile looking saleswomen in the jewelry store only to end up disarmed ,stripped ,humiliated and prey to their deviant desires
