At first, he still has a conscience, as he is aware of his actions and the possible repercussions of said actions. Macbeth’s mental deterioration begins to show itself as he becomes extremely paranoid. His paranoia starts to be shown as he plans to have Banquo killed. Along with his prophecy to become king, the witches also tell Banquo, Macbeth’s friend, that his children will become king. This makes Macbeth think that Banquo will try to kill him to gain the crown. In response, Macbeth decides to hire men to kill Banquo. This shows that Macbeth has lost the ability to make rational decisions, and he makes actions without checking the validity of the “proof” for his actions. The next point at which Macbeth’s worsening mental state is shown is at the dinner he is at the night Banquo is murdered. During the dinner, Macbeth sees an apparition of Banquo; reacting by asking the other lords “Which of you have done this?” (Shakespeare 3.4.52).

Lady Macbeth does not show many more signs of mental deterioration until her last scene, in which Lady Macbeth begins to sleepwalk. She has now asked to have to candlestick with her at all times, as she has become terrified of the dark: “She has light by her continually. ‘Tis her command” (Shakespeare 5.1.22-23); probably because she killed Duncan under a cloak of darkness. She then recounts the deaths of Duncan, Lady Macduff, and Banquo. Thinking about the deaths that have happened at the hand of both her husband and herself, Lady Macbeth decides to commit suicide. This shows that, despite the fact that Lady Macbeth does not outwardly show any guilt or remorse for the murders, she is fighting a brutal internal battle. It is her conscience and her love for her husband at the
