Step-by-step explanation:
Macbeth's Emotion Toward the Doctor
In the passage from Act V of The Tragedy of Macbeth, Macbeth expresses a sense of desperation and frustration towards the doctor. Macbeth desperately yearns for a remedy to cure his wife, Lady Macbeth, of her tormented mental state, evident from her sleepwalking and guilty ravings. When he asks the doctor to "minister to a mind diseased," he is looking for a cure that he hopes will erase the troubles plaguing Lady Macbeth's conscience. However, the doctor's inability to provide a medicinal solution to such a deeply rooted psychological issue evokes Macbeth's frustration. Shakespeare's depiction of Macbeth's interaction with the doctor highlights the limitations of medicine when faced with the consequences of moral transgressions, in this case, the guilt derived from the murderous actions driven by Macbeth and his wife's ambition.
