I think that it is the last choice that makes the most sense to me so the the answer is number 5.The other themes aren't true or don't go along with the excerpt."The insane have no sense of time doesnt work because that theme is not true in this case because it does not mention time that much in the excerpt.So, we can eliminate this theme. "The insane are obsessed with mortality isn't true either because he never said that he liked killing the man. He even says "I loved the old man." So we can eliminate that. "The insane are incapable of using deception.isnt true becuase he did not deceive anyone and "The insane lack imaginationisnt true because he does not lack imagination.
