Comment on the following: "Lady Macbeth is a more noble character than her husband."
Lady Macbeth forces herself to set aside all feelings of mercy to push him toward the destiny she believes is his. So in this sense, we might argue that she is fulfilling her duty as the wife of an ambitious nobleman. On the other hand, Macbeth's objections early in the play are moral, and she seems to be free of such concerns, adopting the stance that the ends justify the means. Many of her comments, such as her assertion that she would murder her own newborn baby rather than fail to fulfill a promise, reveal a fundamentally evil woman. However, as the murders begin to add up, we see that Macbeth loses sight of any sort of morality, but Lady Macbeth is clearly torn apart with guilt. By the final act, she has fallen apart, as the famous "out damn'd spot" speech indicates. She breaks under the weight of the decisions she and her husband have made. Nobility might not be exactly the best word to describe her behavior, but we do see her humanity reasserted late in the play even as her husband is transformed into a murderous monster.
