The Island of Dr. Moreau help with homework: How does Wells create an atmosphere of bleak

How does Wells create an atmosphere of bleak hopelessness, and how does this tone function in conveying a moral or spiritual point of view?

Prendick says he finds “a strange wickedness” in Moreau’s choice of the human form as the form he will try to recreate. What about the Beast Folk’s struggle to become human makes them tragic? Does the ability to become a tragic feature extend to animals? How does their struggle reflect fundamental differences between humans and animals?
