What are two internal conflicts in the story?

One internal conflict would be the fact that Rainsford has to rethink his theory that hunters killing their prey is not murder. That table turns when Rainsford becomes the hunted. 

His second internal conflict would be found in what he needs to do to survive. Rainsford would never have considered murder a moral activity. None-the-less, killing Zaroff is his only option is he wishes to survive his ordeal.
