<human>: The person who raped her is someone I knew well last year and I feel like if it wasn't for me introducing them, this never would have happened. He lives on the same floor as my friend (in a dorm) and they started getting friendly. One night, he was drunk and went into her room and passed out. Later in the night he woke up and started raping her while he was still drunk, she tried to get him to stop but couldn't. Apparently this kid always carries a knife on him too, and he put a knife on the dresser next to the bed when he came into the room. 

Anyway, as you can imagine, all I want to do is beat his face into a pulp but I'm level-headed and I know that I can get into a heap of trouble for that. Not because he would necessarily say something to someone but just because there's always people around. Also, he carries knives around...

Anyway, what can I do? I know the hall director talked to my friend after he was informed of the 'alleged assault' but that was as far as that went. I really want to post the assholes name and facebook profile on Reddit and let you guys go to work but I figured I would ask the community first.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Female friend was raped by male ex-friend and female friend didn't tell cops and doesn't see the point to anymore anyway. She does want me to beat the shit out of him though. What do I do?
