Shakespeare presents the relationship between Macbeth and Lady Macbeth as initially strong and equal, but it deteriorates due to guilt and paranoia.
Step-by-step explanation:
Shakespeare presents the relationship between Macbeth and Lady Macbeth as initially strong and equal, with both characters having a say in their decisions. Lady Macbeth's love for her husband and desire for his success drives her to encourage him to commit terrible acts. However, as the play progresses, their relationship deteriorates due to the guilt and paranoia that consume them. Macbeth becomes more independent and secretive, while Lady Macbeth's guilt leads to her descent into madness.
