2. One example of dramatic irony from scene one is when Macbeth says that his old friend is the only man in Scotland that he fears because they used to be like brothers. It’s also ironic that he pressures the murderers into killing Banquo the same way that Lady Macbeth pressured him to kill Duncan. Another example would be when he tells Banquo that they should talk about how Malcolm and Donalbain might be conspiring against his crown. This is ironic because Macbeth is going to have Banquo killed because he thinks he might conspire against him.
