Lady Macbeth is a ruthless, ambitious woman, who acts on the information her husband gives her about the witches prophecy without hesitation or thought of consequence in the beginning of the play.
Lady Macbeth is a manipulative wife who believes that her husband is not man enough to commit the murder. She thinks that he is too soft. In fact, she believes that masculine men behave aggressively and act violently. She wishes that she were a man, so that she could act on the prophecy and kill the king.
Lady Macbeth, one of Shakespeare's most evil female characters, is depicted as a harsh, cruel and power hungry woman with no conscience. The only evidence that is given that Lady Macbeth possesses any gentle sensibility is when she tells her husband that she could not murder King Duncan in his bed, because he looked like her father sleeping. At first this is the only vulnerability that is expressed about the character.
Later in the play, she does get consumed with conscience and ends up suffering from terrible paralyzing guilt.
