Lady Macbeth and her manipulative ways are one of the reasons for the downfall of Macbeth also her desire to attain power through him was what truly sets the downfall off. Lady Macbeth uses many ways such as persuasion, manipulation and belittlement in to making Macbeth commit the first murder. Lady Macbeth thinks that she has to take control of the situation of Duncans murder in order to succeed as she knows that Macbeth is too much of a coward to do it by himself. Yet do I fear thy nature it is too full o the milk of human kindness, this was written in the letter sent to Lady Macbeths from Macbeth, it tells us that even Macbeth himself doesnt believe he is capable of murdering Duncan. Even though Macbeth has the ambition and wants to be powerful he knows in himself that he doesnt have the guts to do it. Lady Macbeth also knows it which is why she gives him the push he needs to commit the murder even though he knows it is wrong he allows Lady Macbeth to persuade him to do it.
When Macbeth finally sees senses in that killing Duncan is wrong he tells Lady Macbeth, We will proceed no further in this business. Lady Macbeth doesnt like the idea that he has changed his mind, so she begins to verbally attack him. When you durst do it, then you were a man; and to be more than what you were, you would be so much more the man here Lady Macbeth belittles Macbeth by questioning his manhood and then saying that he would be a much greater man if he were to go through with the deed. With Lady Macbeth questioning him like that Macbeth allows himself to be swayed by his wife in to going through with Duncans murder and ultimately choosing to follow a dark path of death and destruction which was one of the first stages to the downfall and was simply shown to him by Lady Macbeth.
