Final answer:
Macbeth and his wife do show evidence of deep love and partnership at the beginning of Shakespeare's play, which is indicated by their mutual ambition and intimate correspondence.
Step-by-step explanation:
The question of whether Macbeth and his wife love each other deeply at the beginning of Shakespeare's play can arguably be answered as true. In the text, there is evidence of a strong bond and partnership early on. Macbeth refers to his wife as his "dearest partner of greatness" in a letter, showing high regard and intimacy. Similarly, Lady Macbeth is passionately ambitious for her husband and challenges him to fulfill their shared ambitions. This level of interconnectedness and mutual ambition indicates a deep, if flawed, affection. For instance, when Macbeth hesitates to murder King Duncan, Lady Macbeth questions his love for her, equating their shared quest for power with the strength of their relationship.
