Which event is an example of irony in “Macbeth”?

Irony is a literary device that occurs when the opposite of what is expected happens. In "Macbeth," there are several examples of irony, but one of the most significant is when Macbeth vows to find the murderer of King Duncan, when he himself is the one who committed the murder. This is an example of dramatic irony, where the audience is aware of something that the characters are not.

Macbeth's vow to find the murderer is ironic because he is the one who committed the crime, yet he is acting as if he is innocent. This creates tension and suspense in the play because we, the audience, know that Macbeth's words are false, and we can see his guilty conscience starting to take over. The irony of the situation highlights the theme of ambition and the corrupting influence of power, as Macbeth's desire for power and his willingness to do anything to achieve it leads him down a path of destruction.

Furthermore, this example of irony is significant because it foreshadows the downfall of Macbeth. His vow to find the murderer is an attempt to divert suspicion away from himself, but it ultimately fails. As the play progresses, we see Macbeth's guilt and paranoia take over, leading to his downfall and eventual death. The use of irony in this way helps to emphasize the tragic nature of the play and its themes, as we watch Macbeth's ambition and desire for power consume him.
