Final answer:
The universal theme of the consuming power of guilt is developed through Lady Macbeth's guilt-ridden actions and statements.
Step-by-step explanation:
The universal theme of the consuming power of guilt is developed in this excerpt through multiple elements.
Firstly, Lady Macbeth still having Duncan's blood on her hands symbolizes the weight and permanence of guilt. This visual imagery highlights the all-consuming nature of guilt.
Additionally, Lady Macbeth speaking about her actions in front of others and expressing her belief that she cannot wash the blood off her hands further emphasize the psychological and emotional impact of guilt.
Lastly, the suggestion that Lady Macbeth is looking for the wife of the Thane of Fife connects guilt to the consequences of her actions and the potential for guilt to spread and affect others.
