He is seen in the play to be a noble and courageous general. The three witches prophesied that his children would one day inherit the Kingship of Scotland. He is also very ambitious but the only difference between him and Macbeth is that he does not do evil things with the aim of fulfilling prophecies of the witches. His character seems to irk Macbeth because it represents what Macbeth wants to be but has not managed to be. When he is murdered by Macbeth, his ghost haunts Macbeth and he feels guilty for what he did.
