Ambition can be seen as the cause of Lady Macbeth's path throughout the play. This is shown throughout her use of speech in the play, as her speech changes and develops as the play progressively becomes darker with the development of Macbeth's rise and fall.
This is because the use of rhyme emphasizes the unnerving presence of the witches.

This can initially be shown in Act 1, when Macbeth mentions how Nature seems dead, wicked dreams abuse the metaphorical language used here captures the peak of Macbeths anxiety because the pressure on him to commit to follow the plan has changed his metal state so much so that nature representing order and life seems dead which implies a destruction of order and life. This could symbolise how this pressure has destroyed the nature within Macbeth, as if he feels that by committing himself to such a terrible act he is destroying his life within him, the nature and is disrupting the order in...
