Final answer:
Lady Macbeth uses psychological manipulation and emasculates Macbeth to convince him to commit murder.
Step-by-step explanation:
Lady Macbeth uses various tactics to convince Macbeth to commit murder. One of the main ways she does this is by belittling him and questioning his manhood. For example, she mocks his courage and calls him a coward when he hesitates to carry out the plan. She also manipulates his desires and ambitions, appealing to his desire for power and greatness. In Act 1, Scene 7, she challenges his masculinity by saying, "Art thou afeard To be the same in thine own act and valour As thou art in desire?" This shows how Lady Macbeth uses psychological manipulation and emasculates Macbeth to make him feel inferior and obligated to prove himself through the act of murder.
