We first see Lady Macbeth when she is reading the letter from her husband about the prophecies of the witches, ‘Whilst I stood rept in the wonder of it came masses from the king, who all hailed me Thane of Cawdor, by which title, before the weird sisters saluted, and referred me to the coming on of time with “Hail King that shalt be!’ At this point she immediately knows that they will kill Duncan, ‘The raven himself is hoarse that croaks the fatal entrance of Duncan under my battlements…unsex me here, and fill me from crown to toe top full of dearest cruelty.’ This is the point at which Lady Macbeth decides to take fate into her own hands so that she and Macbeth can reach power even if it means denying human nature and feeling. This shows us how power-hungry she is. It also reveals to us the lengths that she will go to achieve her obsession. When her husband shows signs of weakness and wants to back out of her plan she goads him until he changes his mind, ‘I have given suck, and know how tender `tis to love to the babe that milks me, I would while it was smiling in my face, have plucked my nipple from boneless gums, and dashed the brains out, had I sworn so as you had done to this.’ Here she uses her clever powers of persuasion in a way that Macbeth can’t really argue with. She uses their relationship and undying love and devotion to pressurise and motivate Macbeth into killing Duncan. This expands on my previous analysis because it demonstrates how she achieves her goal, by using her intelligence and cunning in a composition that in theory is fool proof. Ambition drives her, ‘Wouldst thou have that which esteem’st the ornament of life, and live like a coward in thine own esteem letting ‘I dare not’ wait ‘I would’ like the poor cat i `th’ adage?’ She is even prepared to renounce her male instincts ‘unsex me’ because if she was a man she could be king. She knows no human feeling, ‘Make thick my blood.’ She wants to become thick blooded, not literally but in mental state. Basically she wants to become insensitive and free from vulnerability of an attack of conscience. After the murder Duncan, Macbeth becomes stronger than his wife as he strives to protect what he has taken by violence, ‘There shall be done a deed of dreadful note…. Be innocent of the knowledge, dearest chuck til though applaud the deed.’ Before Lady Macbeth told Macbeth to leave things to her but now Macbeth is telling her not to worry about things, that she doesn’t need to know about it because he will deal with things. Character wise, there has been a complete reversal between Lady Macbeth and Macbeth and now with the use of chuck, he is almost patronising her. There has been a change of roles in their relationship and now he is the more decisive of the couple. Before the murder of Banquo she recognised that they have not gained happiness, ‘Nought’s had, all spent, where our desire is not go without content (Act 3, Scene 2). At this point she recognises that although they have gained the crown they have lost everything else, therefore suggesting that she now thinks what they had before was better than being king and queen of Scotland This evidence that she had lost her hunger and desire for power, which she once had.
