Final answer:
After Duncan's murder in 'Macbeth,' both Macbeth and Lady Macbeth initially appear alike in their shared ambition and ruthlessness. They soon diverge as Lady Macbeth maintains her composure and pragmatic approach, whereas Macbeth is consumed by guilt and paranoia, which causes a rift in their relationship.
Step-by-step explanation:
After the murder of King Duncan, both Macbeth and Lady Macbeth display a complex interplay of similarities and differences. Initially, they share a common ambition and a willingness to break moral boundaries to achieve power; this compels them to conspire and commit the heinous act. However, following the murder, their reactions start to diverge significantly. Lady Macbeth remains composed and pragmatic, trying to cover up the crime by instructing Macbeth to 'go get some water, And wash this filthy witness from your hand.' In contrast, Macbeth is haunted by his guilt, as demonstrated when he says, 'Who can be wise, amazed, temperate and furious, Loyal and neutral, in a moment? No man.'
Despite their unity in ambition and the act of murder, their approaches to the aftermath are vastly different. Lady Macbeth takes charge, remaining focused on maintaining their facade, while Macbeth becomes increasingly paranoid and consumed by guilt. Their partnership begins to fracture as Lady Macbeth is unable to comprehend Macbeth's gradual unraveling and Macbeth is isolated by his spiraling thoughts, leading to increased tension between them. These reactions are indicative of their underlying personalities and the contrasting ways they handle the psychological consequences of their actions.
