Lady MacBeth is one of Shakespeare's greatest and most intriguing female characters. She is evil, seductive, and witch-like all at the same time. However, during the play we see her in two different ways. At the time when we first meet her, she is a brutally violent, power wanting person, and later on she turns to a shameful suicidal grieving woman.
At the beginning of the MacBeth, Lady MacBeth is very vicious. She thinks nothing of killing King Duncan. She has no sense of what is wrong and right, and believes that it is perfectly normal to do the deed of murder. She states that to not go through with the deed would be horrible to yourself, and that you would be a coward in your own eyes. "Wouldst thou have that which thou esteem'st the ornament of life, and live a coward in thine own esteem," (act 1, scene 7, line 41) She states that if she was MacBeth and did not jump at this perfect opportunity, that if a child, being fed at her breast, whereas Duncan is, king, she would tear it from her and "dashed the brains out" (act1, scene 7, line 58) to have the opportunity MacBeth does. This shows how mad and sadistic she was. She had absolutely no self- conscience, and thought nothing about the wrong they were soon to commit. Later on, after the murders, she, unlike MacBeth, still shows no signs of a conscience. She is very cool and collected, while MacBeth hallucinates and goes temporarily mad. Lady MacBeth on the other hand, takes everything calmly. She takes the daggers back to the King's room, smears blood on the drunken guards, and attempts to destroy all evidence of MacBeth ever being there. She knows what needs to be done and does it without any hesitation or fear.
However, it is later on in the story, that it is revealed to us that Lady MacBeth's conscience is strong. When sleep walking one night, Lady MacBeth begins talking about spots of blood on her hands. "Out damned spot! out, I say! One; two: why, then 'tis time to do't Hell is murky! Fie, my lord - fie! a soldier and afeard?" (act 5, scene 1, line 25) When at first she believes that "a little water clears us of this deed" (act 2, scene 2, line 67), and now she can smell the blood on her hands still, and "all the perfumes of Arabia will not sweeten this little hand" (act 5, scene 1, line 37). She now realizes the consequences of what she has done. She knows that the sin will be on her soul forever, and that nothing will be able to cleanse it. She realizes "What's
