Throughout the play, it is Lady Macbeth who plans and urges her husband to kill King Duncan. In Act One, Scene 7, Macbeth agonizes about whether he can kill Duncan and doesn't feel like his ambition is worth committing regicide. Shortly after, Lady Macbeth enters and Macbeth tells her that he cannot go through with the murder. She then begins to question his manhood and asks Macbeth if he is a coward. Lady Macbeth tells Macbeth that if he follows through with the plan, he will be considered more than a man. She also makes Macbeth feel ashamed by telling him that if she had known he was such a coward, she would have "dashed" their baby's brains out. Macbeth then considers the possibility of failure, but Lady Macbeth quiets his concerns by assuring him that if he has courage they won't fail. She goes on to explain the plan which includes framing Duncan's two chamberlains then acting like they grieve Duncan's death. Lady Macbeth finally succeeds in giving her husband confidence to go through with murdering Duncan.
