Lady Macbeth is Macbeths wife, and she has the most influence on him. She knows his weaknesses, and she knows how to talk to him in order to touch his weakest points and make him doubt his own actions. One thing that she does is that she questions his masculinity. For example, she says that he is not man enough to kill Duncan, to obtain his position as king. She knows that it hurts Macbeth’s pride. He will act, only to prove his masculinity. Lady Macbeth also courages and helps him. She tries to make it as easy as possible for him to kill Duncan. She makes the guards drunk, and she puts the daggers in place, so that the only thing Macbeth has to do, is the actual action of murdering.
