Describe the characters of King Duncan and Lady Macbeth, providing specific examples from the play.

Here are the descriptions of the characters:

i) King Duncan
King Duncan is portrayed as a benevolent and trusting ruler. He is a respected figure whose murder is seen as a profound violation of natural order. An instance of his character is his generosity in rewarding Macbeth with the title of Thane of Cawdor for his bravery in battle, showing his appreciation and trust in his subjects. He also expresses deep gratitude and affection towards Macbeth and Banquo.

ii) Lady Macbeth
Lady Macbeth is a fiercely ambitious and manipulative character, initially more ruthless and strong-willed than her husband. She is instrumental in pushing Macbeth towards regicide. A key instance of her character is her persuasion of Macbeth to murder King Duncan, where she challenges his masculinity and devises the plan for the murder. Later, she demonstrates her resolve by planting the daggers on the guards. However, her character also shows a descent into guilt and madness, exemplified by her sleepwalking scene where she tries to wash imaginary blood from her hands.
