The consequences of Macbeth’s hamartia start to fully show in Act 3, where ambition starts to fully take over his life and more murders are committed to maintain his position as King of Scotland. Act 3, Scene 4 acts as a turning point in the play as it displays Macbeth’s guilty conscience. The banquet scene is supposed to be the pinnacle of his reign, however the introduction of Banquo’s ghost disturbs this.
