Not the main character but the Unreliable Narrator

Brave New World (Aldous Huxley)

Ralph Denham was so real for this

"Man, in this earthly life, though capable of many evils, is not capable of them all at once, inasmuch as one evil corrects and counteracts another just as one poison frequently corrects another. In hell, on the contrary, one torment, instead of counteracting another, lends it still greater force: and, moreover, as the internal faculties are more perfect than the external senses, so they are more capable of suffering."
