The problem of evil is something that any theist has to face. In formal theology it’s called theodicy. There’s usually two angles to theodicy. To try to understand how evil can exist in a world created by a good God, and to create a vision of God that is is consistent with the reality that the world is fucking awful. There are a bunch of classic Christian theodicies by Augustine, Iraneus, Origin, and modern theologians.
I agree with some modern theologians in that theodicies normalize and forgive evil in the world. They normalize violence, inhumanity, abuse, war, horror. This darkness ends up becoming part of the system: God has a plan, that is why a child is raped. A child is raped because of our sin, our corrupted nature. A world with horrors like a child raped is necessary for us to develop spiritually and know God. All this legitimizes these horrors. Such theology becomes the potential basis for evil.
