Actually, no matter what, a person's actions can't be blamed on anyone, but if anything I'd say the 666 pentagram (sp?) styling I hate everyone, go evil stuff, no one understands me attitude is what does it. Such as marilyn manson, the slipknot guys, among others who were those kind of kids in the 80's, grew up and are teaching their new ideal's to the new generation of kids who feel unwanted or out of place expressing what the kids were thinking in approval, that they have nothing to lose. If you have bad abusive parents that leads to that feeling of you are unwanted. That built anger is directed towards everything they do, this stuff is not true with everyone, just things I've seen with different people I've known in my life.
