I believe in God but found the arguments in The Brothers Karamazov (and yes I read the book) to be misguided. There’s a part in particular where a quasi-villainous character loses faith in God and suddenly goes right to murdering other characters who have been getting on his nerves. The whole thing takes Nietzsche to a whole new level. We aren’t the sum of our schools of thought; in fact, in my faith, God doesn’t really care about faith as much as he cares about how good we are. I’ve never met anyone before who doesn’t have at least some innate sense of some kind of boundaries.
