Lady Macbeth
During Macbeth there are many factors that lead up to the murder of Duncan, and one of the min ones was Lady Macbeth. She contributes many things such as persuading Macbeth, assuring him that it is the correct thing to do, she fills herself with pure evil and becomes intoxicated by the thought of being queen.
She persuades Macbeth to kill king Duncan, because at first he tried to put it completely out of his mind. She tells him that ‘When you durst do it, then you are a man”. This is taunting Macbeth, but this also persuades Macbeth because he does not want to seem weak in front of his wife. He wants to impress her, and therefore when she mocks him he has to commit this act. Furthermore the fact that she would “Have pluck’d my nipple out, from his boneless gums // And dash’d the brains out” further emasculates Macbeth. She is saying that she would coldly slaughter her own baby rather than go back on what she had said before.
She gives Macbeth confidence when she says “We fail!” because it attempts to erase the terror from Macbeth’s mind. By doing this she assures that not only will he not be worried but she is also reassuring herself.
She fills herself and Macbeth with cruel poison, which allows the pair to commit the act. “Fill me from the crown to the toe-top-full Of direst cruelty” By filling herself with poison it makes it possible and even easy to commit this murder. She wants to be almost made out poison and horrible substance.
She becomes obsessed with becoming queen, which put even more pressure on Macbeth to please his wife. She says that Macbeth is ”too full o’ the milk of human kindness” showing that she will do anything to become queen. Also by thinking to herself and expressing this lust to Macbeth she further put the idea of being king into Macbeth’s mind.
