Connection to Macbeth

In Macbeth, the audience feels throughout the play that Macbeth’s slaying of the innocent Duncan was unjustified. Even though Macbeth feels guilty and has doubts and scruples, he still goes through with the act, which makes us unconsciously feel that he should be punished and not rewarded with the kingship. The audience has a need for closure and to purge all of these emotions about Macbeth. This need ultimately leads to the death of Macbeth, as it is the simplest and possibly the most satisfying way to purge the emotional baggage associated with Macbeth and because he finally gets his justice.
