Fear, this motivates us to do many things no matter if they are right or wrong. In the
Play Macbeth it was fear that was the main motivating factor that influenced the
outcome of the play. This can be proved by the subsequent murders that followed
after Duncan's, why were these committed? Because Macbeth was scared of being
caught and having to pay for the wrongs he had done. Also look at Lady Macbeth,
he constant washing of her hands, sleepwalking and other behavior like this. All
done out of fear, and like her husband fear of being caught. The final piece of proof
I offer is Macbeth's actions, they were all due to fear, not only of being caught but
of the witches' prophecies, he was scared of them coming true and tried to stop
them from happening. This whole play was inspired by fear and what it and do to a

King and after him none of his family will follow.
Only for them; and mine eternal jewel

To make them kings, the seeds of Banquo kings!
[Act III, S I, L 72-75]
Here Macbeth realizes that if something is not done to Banquo, then his sons will
become King. Macbeth can't have this, he's already worried that his soul will go to
hell for what he's already done. His fear become evident in this scene also, "But to
be safely thus: our fears in Banquo Stick deep;" [Act III, S I, L 53-54] Macbeth
then has Banquo murdered, however his son Fleance escapes in the attack. Next
Macduff refuses to accept Macbeth as king and flees to England to join Malcom.
And also the witches tell him to
