Some of the Scottish lords are discussing Macbeth's state of mind and have come to the conclusion that they will help Malcolm and Macduff fight against Macbeth. Of course, Macbeth isn't really concerned because the prophecy, he believes, insures that he cannot be killed by any man born of woman. Macbeth soon confronts Macduff and learns that Macduff was ripped from his mother's side and not born naturally. Thus, Macbeth is killed by Macduff, just as Macbeth had conquered the other Thane of Cawdor. Malcolm then becomes the rightful King of Scotland
