You did not kill the fish only to keep alive and to sell for food, he thought. You killed him for pride and because you are a fisherman. You loved him when he was alive and you loved him after. If you love him it is not a sin to kill him. Or is it more?

"I killed him in self-defense," the old man said aloud. "And I killed him well."
Besides, he thought, everything kills everything else in some way. Fishing kills me exactly as it keeps me alive. The boy keeps me alive. I must not deceive myself too much.
