Destiny

Destiny was a large role in the play Macbeth, Destiny or Fate, caused Macbeth do to many of the things he did. For example: If the three witches had not said anything about Macbeth becoming King of Scotland he most likely wouldn't have plotted to kill the King. Although it is still possible he could have plotted to kill the King it would be far less likely if he didn't think it was his destiny. The idea of destiny then took over the play as it took over Macbeth, the witches showed Macbeth things that he was already afraid of causing him to make rash decisions which change the course of the play. For example when the three witches tell Macbeth that Banquo's bloodline will eventually take Macbeth's place on the throne, Macbeth tries to have Banquo and his son killed. This then starts the war with Macduff because he is already suspicious of Macbeth for killing the King but this sets him over the top.

Macbeth and Banquo meeting the withes for the first time as they predict, both their destinies.

 Destiny also plays a role in the readers mind, the three witches give him circumstances that seem impossible; For example when they said "because nobody born from a woman will ever harm Macbeth." this makes people believe he cannot be killed, yet he is killed when he finds out Macduff was cut out from a women and not born the regular way. All these prophecies make the readers think how different things will play out which makes the play very interesting to read.
