Metaphors are utilized in this scene to help portray Macbeth’s feelings and aid in him expressing them. In this scene, Macbeth and Lady Macbeth discuss how even though they are now the royal family they do not feel satisfied because they cheated their way into kingship. Macbeth says “O! full of scorpions is my mind”. This is said when he also comments on Banquo and Fleance, who Macbeth now considers as enemies. Because of this, the metaphor can mean two things. The first is that Macbeth’s find is uneasy and full of darkness and that scorpions represent this. It also means that the knowledge of Banquo and Fleance’s future stings his mind as a scorpion does. It stings his mind because he has become paranoid and believes that killing them both will guarantee his position as king forever. A metaphor is used here to describe his mind, and so a language feature that creates images can be very effective in this particular case.
