The contrast between Macbeth and Lady Macbeth is an example of peripety. Macbeth is grieved after he kills King Duncan. He talks about his blood stained hands. Lady Macbeth reassures him that using soap and water will take care of it and that the murder was no big deal. Later, we see a change in her when the guilt starts to affect her with hallucinations and confessions during her sleep walking. Lady Macbeth, subconsciously is now trying to wash away the evidence on her hands. By the end, Lady Macbeth is ridden with her own guilt which may have lead her in taking her life.
