 Studying William Shakespeare's play Macbeth? Let's discuss key quotations and word-level analysis relating to the character of Macbeth when he kills King Duncan. In Act 2 scene 2 after Macbeth kills King Duncan he is horrified by his actions. He says there's one did laugh in his sleep and one cried and the repetition of one shows his disgust with himself. He mentions murder and this exclamatory sentence shows his deep remorse at going against the King and committing Regicide. He later says God blesses and Amen and this religious language ties into the divine right of Kings. He is aware that he's gone against God's will by killing the King. The alliteration of age and had hang men in hands show that he feels like he's beyond redemption. He tells Lady Macbeth I could not say Amen and this declarative sentence shows how far he feels from God how disconnected after killing the King and going against divine right of King.
