They give him three more prophecies: that Macbeth will not be defeated until the forest reaches Dunsianne, that a man born of a woman cannot defeat him, and that Macduff must beware. Now Macbeth is completely deluded as he believes he himself is invincible, but he is still paranoid enough to kill Macduff even though he doesn't think any harm can be done to him. He sends assassins to take care of Macduff, who kill Macduff's wife and children when Macduff himself is not there. At this point Macbeth has become a tyrant, so caught up in his delusions and his power that he is no longer anything like he was before. When the English army arrives he is confident that no man born of woman will be able to harm him. “You were born of a woman. But swords make me smile, weapons laugh in contempt, wielded by a man born of woman. When Macduff reveals that he was not born of a woman, Macbeth recovers from his delusions and realizes the harm he has done. Macbeth realizes at this point that he has committed so many murders and unnatural acts for nothing, and this whole matter has never served him well, having come out of his delusions, his thoughts end with his thoughts.
