After killing Duncan, there is a change in Macbeth, and it is good that he needs to kill. Banquo, Macbeth's close friend, is visited by the witches, who then tell him the news that he will not be king, but that his descendants (children) will. Upon hearing this, Macbeth becomes angry, fueled by jealousy, and decides to have Banquo, his close friend, killed. Eliminating every possible threat makes sense to Macbeth, as if it is the only way to ensure that he is king. Later however, it weighs heavily on Macbeth, realizing what he has done. (Act 3; Scene 4; Lines) A ​​dramatic change is first observed at the banquet hosted by Macbeth. Here he invited the most respected roles like the Thane of Scotland. During the party, Macbeth is visited by Banquo's ghost, whom only Macbeth can see. It is a disturbing sight not only for Macbeth, but also for his guests since Macbeth is the only one who can see Banquo. Rather than always being with them, Macbeth and Lady Macbeth are driven to madness, essentially trapping themselves in their minds. A first sign could be hand washing. Lady Macbeth says, “A little water cleanses us from this deed” (Act 2; scene 2; Line 86), she believes that they can literally wash the blood from their hands and everything should return to normal. Later it became clear that washing your hands was not a solution.
