The insecurity of MacbethMacbeth, the main character of William Shakespeare's tragedy, Macbeth was not secure in his manhood. This insecurity led to Macbeth's downfall as he felt the need to prove himself to Lady Macbeth. After proving himself by killing Duncan, Macbeth became impervious to murder. At the beginning of the play, Macbeth showed his love for Lady Macbeth in different ways. He tells her of his feelings towards her “My dearest love” (act I, scene v, l 58). Macbeth listens to what Lady Macbeth has to say and takes her advice into account whenever he makes a decision. He also has great love for her and does his best to make her happy no matter what it takes. Lady Macbeth convinced Macbeth that he was not a man unless he committed Duncan's murder. She threatens his manhood by saying: When you dared to do it, then you were a man;/And to be more than what you were, you would be/Be all the more the man (act I, scene vii, l 49 -51).Slowly Lady Macbeth manipulated his mind into believing that the right thing to do was to kill Duncan. Macbeth had decided that to prove his manhood, he must commit this horrible act. After Macbeth committed the crime, he felt that his soul could never be cleansed, no matter what he did. He said: They pluck out my eyes!/Will all the ocean of great Neptune wash away this blood/Cleanse my hand? No; it is my hand that goes rather / The innumerable incarnadine seas, / Make green red (act II, scene iii, l 58-62). This shows that he really didn't want to kill Duncan, but he did it to prove himself to Lady Macbeth and become king. In the end, he was no longer afraid and had killed not only Duncan but many other people as well. He now had different views than he had at the beginning of the play. Macbeth realizes that he is no longer afraid “no, nor more fearful. » (Act V, scene vii, l 9). He's considered a man now, but he doesn't like the fact that he killed all those people..
