Remember the copy-cat killers? Two teenagers go off and kill their school mates in Colorada. They were fans of Marylin Manson, listened to his music; and their website reflected the music they listened to. They may have not been good people to start with. They may even of had a good homelife; but they learned how to do evil by all those sources mentioned above. And now we see that other teens learned from them, picked up their parent's guns, and shot their school mates as well. Evil can be learned...re: copy-cat killers.
