The Aftermath of Murder
Right after killing Duncan, Macbeth is completely falling apart. His hands are covered in blood, and he's obsessing over every tiny detail from the murder scene. He tells Lady Macbeth about hearing servants cry "Murder!" in their sleep, which shows how paranoid he's already becoming.
The most significant moment happens when Macbeth couldn't say "Amen" after the servants prayed. This reveals something crucial - by committing murder, he's spiritually cut himself off from God's protection. For Shakespeare's audience, this would have been absolutely terrifying.
Lady Macbeth tries to stay practical and calm, telling him not to think about what they've done so deeply. She warns that overthinking will "make us mad" - which is actually foreshadowing what happens to both of them later in the play.
Key insight: Notice how differently they're handling the guilt - Macbeth is spiralling emotionally whilst Lady Macbeth is trying to stay in control.
