This speech is said soon before Duncan is to arrive. The first impression anyone would get from reading it is that she is trying to psyche herself up for something that she needs to do. Lady Macbeth is obviously a strong willed woman and knows what she needs to do but her feminine sense of being gentle seems to be pulling her back. She feels she needs to convince herself into doing what is wrong.
             Lady Macbeth robustly declares that she knows what she needs to do in the speech. Her only problem is she has trouble making her overlying sense of conscience step back and allow her to do what her mind tells her she needs to accomplish. She knows that her stability must overcome her husbands instability and must play the role of the man if she wants to accomplish what needs to be done.
             "That my keen knife see not the wound it makes." She doesn't want to remember or know what has to be done but knows it must be in order for Macbeth to take the throne. She is in a battle with herself between what is morally right and her desires.
             Her comments about being a woman show that she needs to overcome her overlying sense of gentleness to accomplish her goals. "Come to my woman's breasts" and "unsex me here" are both quotes that portray inner battles that she needs to conquer.
             Without Lady Macbeth, Macbeth would not have the inner strength to do what he has to do to take the throne, and Lady Macbeth realized it. She had to be the strong force behind the terrible things done.
