OH NO YOU DIDN'T WEIRD SISTERS

The weird sisters are very powerful on the prophecies because the sisters told Macbeth what was going to happen and it actually came true. I don't think so because when the witches told Macbeth what was going to happen he believe that he was going to become king. If the witches never told him about it he would never become a murderer and his wife would not put crazy thought in his mind or the witches. I think in the play it probably would happen because mysterious things happens.
