Macbeth's bloody rise to power, including the murder of the Scottish king, Duncan, and the guilt-ridden pathology of evil deeds generating still more evil deeds. As an integral part of this thematic web is the play's most memorable character, Lady Macbeth. Like her husband, Lady Macbeth's ambition for power leads her into an unnatural, phantasmagoric realm of witchcraft, insomnia and madness. But while Macbeth responds to the prophecies of the play's famous trio of witches, Lady Macbeth goes even further by figuratively transforming herself into an unnatural, desexualized evil spirit. So one cant expect better things from this witch..!!!

Lady Macbeth's immediate thoughts may make her appear as thoroughly irreligiously cold and ambitious, but this is not so. To prepare for what she feels must be done she calls on evil spirits to "stop up th' access and passage to remorse" in order to be relentless. Otherwise her conscience would not allow her to act.Lady Macbeth's attempts to suppress her conscience fail. At the end she chooses death because she can no longer bear the torments of her guilt.
