How does Rainsford's perspective on hunting change throughout the narrative?

I suppose when Rainsford is in a tree and reflects that this is how an animal must feel to be hunted tips us off that he has a new attitude. The story, however, is so bizarre that the theme isn't dealt with in any depth. Perhaps Rainsford might think a little more about hunting defenseless animals in the future but I doubt he would start an animal rights movement.
