why macduff?

Brush up your Shakespeare: remember Macbeth? No? A play about how power corrupts, Macbeth takes place in Scotland where a prophecy from three witches (remember "bubble, bubble, toil and trouble?" that's from Macbeth too) turns a once honorable battle hero to a blood-thirsty murderer. Once Macbeth hears the prophecy that he will become the ruler of Scotland, he and his wife plot to kill the king and anyone who tries to stop them. Part of Macbeth's feelings of invincibility come from hearing that "none of women born" can kill him. However, when Macbeth hires a hit on Macduff's family, Macduff vows revenge and succeeds. In one of the play's final scenes, Macduff confronts Macbeth and reveals his family secret: that he was "from his mother's womb / untimely ripped" (Macbeth 5.10.15-16), therefore not "of woman born." Macduff takes the life of Macbeth, restores the peace, and becomes the hero of this Shakespearean tragedy.
