Macduff finds Macbeth, and they begin to fight. Macbeth tells Macduff to surrender because, as he believes, he cannot be killed: “I bear a charmed life, which must not yield to one of woman born” (12-13). Macbeth is telling Macduff that magic (a magical charm) protects him. But then Macduff reveals information about himself that greatly upsets Macbeth: “Macduff was from his mother’s womb untimely ripped” (15-16). Macbeth was born prematurely: instead of being born naturally, a doctor had to perform an operation on the mother (a Csection or Caesarian section) so that the infant could be delivered safely. When Macduff makes this statement or revelation, Macbeth realizes that he has been fooled by the witches. Macduff was not born naturally of a woman. Therefore, Macduff can harm Macbeth.
Macbeth really did not have a charmed life. There was no magic actually protecting him. The witches, though, could foresee Macbeth’s fate. They knew that Macduff was destined to kill Macbeth. But they told Macbeth that prophecy-riddle so that he would act recklessly. And, so, because Macbeth acts recklessly, he is actually responsible for bringing about his own fall.
Macduff and Macbeth continue to fight in this scene. And Macduff slays Macbeth at the end.
Prince Malcolm and his forces are now victorious. They mourn the soldiers who died in battle, and Malcolm promises to reward those who were loyal to him. The reign of tyranny is over.
Malcolm also notes that Lady Macbeth died by committing suicide (35-37). Thus, in one sense, a final connection between Macbeth and his wife is made: both were responsible for their own deaths.
