How does Lady Macbeth manipulate Macbeth?1

Lady Macbeth's manipulation of Macbeth in Shakespeare's play "Macbeth" is a central theme that drives the tragic events of the story. She employs a combination of psychological tactics and emotional manipulation to push Macbeth toward the path of regicide and unchecked ambition.
One of the primary ways Lady Macbeth manipulates Macbeth is by appealing to his ambition. In Act 1, Scene 5, she receives Macbeth's letter detailing the witches' prophecy that he will become king. Recognizing his ambition, she seizes upon this desire and begins to craft a plan to fulfill the witches' prophecy. She understands that Macbeth's vaulting ambition is a weak point she can exploit to manipulate him into taking actions he might otherwise consider immoral or unthinkable.
Furthermore, Lady Macbeth challenges Macbeth's masculinity and courage. In Act 1, Scene 7, she questions his willingness to seize the throne, implying that he would be a coward if he were to back down. She tells him that he would be "so much more the man" if he follows through with the plan to murder King Duncan. This appeal to his masculinity preys on his fear of being perceived as weak or unmanly, pushing him to prove himself through aggressive and ruthless actions.
Lady Macbeth's manipulation also plays on Macbeth's emotional vulnerabilities. She undermines his doubts and fears, using her own unwavering resolve to steel his determination. In Act 1, Scene 5, she tells him to "look like the innocent flower, but be the serpent under't." This metaphor illustrates her advice to maintain a façade of innocence while secretly planning the murder, instilling a sense of confidence in Macbeth. Her unyielding resolve and confidence make Macbeth believe that he can succeed in their murderous plot.
Moreover, Lady Macbeth orchestrates a strategy to ensure Macbeth's compliance. She takes control of the logistics, such as drugging the guards and placing the daggers, minimizing his personal involvement in the details of the crime. This tactic removes some of the direct moral responsibility from Macbeth's shoulders, making it easier for him to proceed with the murder.
Lady Macbeth's manipulation culminates in the sleepwalking scene (Act 5, Scene 1), where her guilt-ridden subconscious reveals the extent of their misdeeds. This scene underscores the psychological toll of her manipulation on both characters, as it becomes evident that they are haunted by their actions.
