Answer:
Macbeth: "What a sad sight." - ACT 2 - Scene 2
Step-by-step explanation:
The line shown above shows one of Macbeth's themes, which is guilt.
The phrase is spoken by Macbeth, who after killing King Duncann, with the influence of his wife, sees his hands are covered in blood and feels guilt and remorse for what he has done. He killed the king out of envy and thirst for power, but he had the king as a great friend, which made him feel guilty for killing a friend and usurping a position that does not belong to him.
