Witches ain't nothing it's all BULL!

I don't think that the same things would have happened it the witches had not told Macbeth anything. Macbeth was only acting had and untouchable because of what the witches said. If they wouldn't have told him he would be acting like a chicken. Not everything that the witches said were true. The witches prophecies did cause a lot of drama because that changed how Macbeth was acting.
