Destiny

I think destiny supports the theme of ambition in this play. I believe Shakespeare wants to tell readers that bad people will never have a good result. Thus, Shakespeare creates destiny for each character and show us that those who immorally pursue their ambitions will have a sad destiny. “Behold where stands the usurper’s cursed head” (V.VIII, 54-55). Macbeth, who always murders others to get his power, is finally killed by Macduff. It is the same with Lady Macbeth. “The disease is beyond my practice” (V.I, 40). She ends up becoming unable to accept her own crimes, and she sleepwalks because she feels guilty. The doctor does not have any method to heal her sleepwalking. “The queen, my lord, is dead” (V.V, 16). She kills herself at the end. Obviously, these characters’ destiny matches with the theme Shakespeare tells us. People who commit crimes because of their ambition will not have a good ending.
