I don't know how to cite it in english, but well the witches were the principal influence for MacBeth for killing the emperor to become this one, they told him that he was gonna win and the throne will be his. And If I'm not mistaken there are some acts that starts with Macbeth entering with the sound of the witch drums. His wife was the bomb taking his hand, the other influence to kill the emperor to take his place .
Now that you mentioned MacBeth influencing Born Villain, I've found more about Sigmund Freud dreams after his father's death in Overneath the path of misery.
