Did Rainsford change his mind about hunting by end of the story?

As a dynamic character in Richard Connell's "The Most
Dangerous Game," Sanger Rainsford does undergo changes in his attitude about hunting. 
In the exposition of the story, for instance, he becomes petulant with his fellow
hunter, Whitney, who sympathizes with the plight of the jaguars that he and Rainsford
are traveling to hunt:

"Don't talk rot, Whitney," said
Rainsford...."Who cares how a jaguar feels?"

"Perhaps the
jaguar does," observed Whitney.

"Bah!  They've no
understanding."

"Even so, I rather think they understand
one thing--fear.  The fear of pain and the fear of
death."

"Nonsense," laughed
Rainsford.

Later in the
narrative, however, as he is being tracked by General Zaroff, Rainsford, who has been
hunted for a day, hears the baying of Zaroff's hounds drawing nearer and nearer.  On a
ridge, he climbs a tree.  Looking down a watercourse, he can see Ivan holding a pack of
dogs in leash.  Knowing that the dogs and hunters will soon be upon him, he swings on a
sapling:

Then
he ran for his life.  The hounds raised their voices as they hit the fresh
scent.  Rainsford knew now how an animal at bay
feels.

In
another character change, Rainsford is at first appalled that the jaded General Zaroff
hunts "the most dangerous game" of mankind.  When at dinner, the general announces his
"ideal quarry," and laughs,

"I refuse to believe that so madern and civilized
a young man as you seem to be harboring romantic ideas about the value of human life. 
Surely your experiences in the war--"

"Did not make me
condone cold-blooded murder," finished Rainsford
stiffly.

Having show disgust
for killing a man in cold-blood, Rainsford, neverthess, returns to the chateau of
Zaroff's and hides in the curtains of the bed only to step out before the general
realizes his presence. When he sees Rainsford, the general congratulates him for having
won the game.  But Rainsford says,

"I am still a beast at bay...Get ready, General
Zaroff."

The general made one of his deepest bows.  "I
see," he said.  "Splendid! One of us is to furnish a repast for the hounds.  The other
will sleep in this very excellent bed.  On guard,
Rainsford."

He had never slept in a better bed,
Rainsford decided.

This last
sentence, coming after the swordfight which elevated Rainsford from a "beast at bay," 
Rainsford finds himself the victor, and now one who obviously has condoned the
"cold-blooded murder" that he disdained at the dinner table with Zaroff on his first
night.

Indeed, Sanger Rainsford changes his opinions about
hunting on two fronts:  He alters his unconcern for the feelings of the prey and
sympathizes later on, knowing how it feels to be a "beast at bay" as he himself is
hunted; also, he abandons his repudiation of Zaroff's "cold-blooded murder" of men and
commits a cold-blooded act of murder himself:

"He never slept better," Rainsford
thought.
