Bravo, bravo, what an end! I rescue all that last part. I loved it. It's as if by repeating his actions with the dog, you are confronting us with an everyday life, with a custom, only in this case it has been different: in one day he has killed two boys. But in this last murder he is relieved to imagine that the boy could have killed his companion. In one way or another he justifies the action and now the death of the boy is less of a burden, it is a relief. A hug for you, @johnjgeddes.
