What is Macbeth driven by?

• What drove Macbeth to treason? Was it the witches and their prophecy? Was it Lady Macbeth and her manipulation? Or was it Macbeth himself and his hunger for power? I think Macbeth would not have acted in such a treasonous nature if he had not received the prophecy from the witches. We see no real corruption in Macbeth previous to the prophecy, or even immediately after. When told he has been given the title of the Thane of Cawdor, he asks why he has been given borrowed robes. When left to ponder the news he then became consumed with power and status. I think If he had never been given the prophecy he never would have been driven to murder.
