Macbeth’s personality throughout the drama changed repeatedly. His mood depended on the actions of not only others, but himself as well. Every emotion had a reason behind it, and that is what the emphasis is in this essay.

In the first act, we see Macbeth as a noble kinsman. He is a brave hero in battle. After gaining the title "Thane of Cawdor," his flaw of ambition takes over. Soon, Macbeth is persuaded into killing King Duncan by his wife. This shows Macbeth’s weakness of pride and ego.

In act two, Macbeth is having some doubt about murdering Duncan. He sees a vision of a dagger which symbolizes his skepticism. He commits the murder and is scared and regretful afterwards. He wishes himself dead and now feels that there is no serious meaning to life.

In act three, Macbeth is angry that he has killed Duncan, and his anger is pointed toward Banquo because the witches have said that Banquo may be the founder of a royal line. Macbeth doesn’t want this to happen. He takes his anger out on Banquo by getting murderers to kill Banquo. Macbeth sees an illusion of Banquo which symbolizes his guilty conscious.

In act four, Macbeth sees three illusions. He turns angry when he has learned that Macduff has fled Scotland to be with Malcolm. He plans to kill Macduff’s family in revenge.

Act five shows Macbeth’s unemotional side as he learns of his wife’s suicide. Macduff leads his army to Macbeth’s castle to fight Macbeth. After a struggle with Macduff, Macbeth is defeated and decapitated.

In conclusion, the mood of Macbeth ranged from noble to vengeful. His own actions had reactions and the actions of others were primarily based on his actions. One murder ignited a spark that ran throughout the entire drama, just to end in tragedy. One lesson to be learned in this calamitous drama is that one physical action can spark a reaction that can be deleterious and even fatal.
