One of my favourite discussions of the problem of evil is the chapter below. It’s a discussion between two brothers regarding God and suffering in the world if the end result is eternal paradise. TW: child abuse, suffering and death. Children are used in the argument specifically because they don’t deserve suffering, they are innocent according to Dostoyevsky (I easily agree).

It’s heavy but worth the read imo, and not unnecessarily graphic.
