Answer:
I would say yes
Step-by-step explanation:
Rainsfold has probably changed his mind about hunting because he had to meet Zaroff in the story. Once he realized that people like Zaroff have taken all empathy out of hunting and started hunting humans, he feels a lot more for the animals.
Rainsford changed from scared and shocked to brave and/or desperate. In the resolution, Rainsford is able to elude the clutches of General Zaroff by jumping off of the cliff. Not only that, Rainsford is able to survive the fall and possibly even be unhurt.
