As I understand it, the three witches do not have any control over Macbeth's fate. What they can do is predict the future--and the future is unchangeable. As far as Macbeth controlling his own fate, that is impossible, although that is exactly what he tries to do. It was inevitable that he would murder Duncan. Shakespeare's message in this play is fatalistic. Whatever is going to happen to Macbeth--or to us--is already predetermined. I think this could be the good beginning for your response. The rest can be done by the writers I trust. Check out the site Prime Writings.
