The moral message of Macbeth is that power corrupts. It shows how easily someone in a position of power can become consumed by it and eventually lose sight of what's important. However, the play also highlights the power of love to conquer all. Lady Macbeth's love for her husband ultimately leads to his downfall, but it also shows the strength of their bond. Additionally, the play emphasizes the importance of friendship in achieving success. Macbeth's trusted friend Banquo serves as a reminder of the importance of having someone to rely on during challenging times. Finally, the play suggests that greed is not necessarily a positive trait. Macbeth's ambition ultimately leads to his downfall and serves as a warning against the dangers of being too focused on personal gain.
