Stars, hide your fires; / Let not light see my black and deep desires Malcolm, the son of King Duncan, is proclaimed Prince of Cumberland this means he is also the heir to the throne of Scotland. Macbeth is willing to push all his principles aside. He knows that murdering King Duncan in order to become King of Scotland is wrong. This is why he says it is necessary to conceal his “black and deep” aspirations. Macbeth also citied that, “â€¦To prick the sides of my intent, but only / Vaulting ambition, which o’erleaps itself / And falls on th’ other”. Macbeth confesses that the he only thing that is motivating him to kill King Duncan is his ambitions. Macbeth’s conscience bothers him throughout the story it is prohibiting him from forgetting all he knows about right and wrong. Here, ambition portrays as something ugly and dark. Macbeth quoted that, “Away, and mock the time with fairest show/ False face must hide what the false heart doth know” (1.7.81-82). Macbeth and Lady Macbeth are going over the plan to kill Duncan.
