* Manipulation: Lady Macbeth plays on Macbeth's ambition and desire for power, reminding him of the prophecy that he will one day be king. She argues that the only way to achieve this prophecy is to kill Duncan.
* Guilt: Lady Macbeth makes Macbeth feel guilty about his lack of ambition and courage. She tells him that he is a "coward" and that he is not worthy of her love if he does not kill Duncan.
* Flattery: Lady Macbeth flatters Macbeth, telling him that he is strong, brave, and capable of killing Duncan. She also tells him that she will always love him, no matter what he does.
* Threats: Lady Macbeth threatens Macbeth, telling him that she will leave him if he does not kill Duncan. She also threatens to kill herself if he does not do it.
In the end, Lady Macbeth's tactics are successful and Macbeth kills Duncan. However, Macbeth is soon overcome with guilt and remorse for his crime, and he eventually goes mad and dies.
