I killed you I killed you, 0 dear one, I did
O: I notice Kreon repeats the words "I killed you" two times. This repetition shows his deep pain and guilt. Before this, Kreon was very proud and never make mistakes. Now he fully accepts that his pride caused the death of his son and wife. This change makes him a tragic figure. I think this use of repetition is a powerful way to show his total ruin.
