In "Macbeth," Shakespeare uses dramatic irony to comment on Banquo's fate by having Banquo unknowingly bring up the witches' prophecy about himself and Macbeth. The audience is aware of the prophecy that Banquo's descendants will be kings, while Banquo himself remains oblivious to this and trusts Macbeth. This creates tension and highlights the contrast between Banquo's innocence and Macbeth's ambition.
