In this final act the overall theme is Macbeth getting defeated by Macduff. In this act as well though Lady Macbeth is also a big part of this act, as she has changed dramatically from the beginning of the play. She was at first a very ambitious person, taking control and pushing her husband to the point where he began to murder. However as we now enter and finish the play she is now a very calm person who has no ambition anymore, and feels terrible about everything that she has done wrong that she wants to harm herself or end her life.
