Macbeth is mentally a weak character that undertakes a drastic psychological change through the play. However, Macbeth then realizes what he has done and becomes guilty. He continues his murderous acts to persuade his dream of becoming King of Scotland. His guilty conscience causes him to hallucinate. Macbeth begins to think that he cannot sleep, “Methought I heard a voice cry “Sleep no more! Macbeth does murder sleep” – the innocent sleep,” (2.2.33-34). Macbeth believes he cannot sleep because he has killed an innocent. Macbeth’s conscious sees Macbeth an evil person now and the “evil Macbeth” will only continue do evil actions. Macbeth believes that he still has the blood of King Duncan on his hands, “Will all great Neptune’s ocean wash this blood / Clean from my hand?” (2.2.57-58). The blood on Macbeth’s hands symbolizes his guilt on him for murdering Duncan. Macbeth thinks that the whole ocean would not be able to wash away evidence of his guilt. His private life and doing causes him to feel guilty he quoted, “I am in blood / Steeped in so far that, should I wade mo more, / Returning were as tedious as go o’er” (3.4.136-138). Macbeth is saying that the situation is already at a bad standpoint and he would like to get the situation over with because he is sick of waiting and living in guilt. He realizes that finding out other bad thing would not make the situation worse because he would still be standing in the same situation. He ends up with a blameworthy sense of right and wrong. His private life consists of poor decisions as well as greed and guilt; this eventually leads to his downfall.
