help needed please

I don't know the song name or artist...
I'm trying to find this one song that I heard a long time ago..

If I remember correctly it's about a guy who, in order to join this gang, has to gangrape some girl... and he does so but upon seeing that the girl is his mother, jumps off a building. Then the singer says that he himself was one of the guys who'd raped the girl.

I think that either just in the beginning or throughout the song there's a piano... or something.... However, I'm pretty certain that the song in general was more rap-ish.

Yes well any and all help is appreciated =)
