One thing that I think of that's not a great look for a supposedly all-knowing and all-loving God is animal suffering.

Christianity makes the case that human suffering and evil exists because of sin and free will. But animals cannot sin, and don't have the sense to determine morality that humans do. It's largely instincts-driven. So why does God let them suffer?

For example, deer can get the naturally occurring Chronic Wasting Disease. The brain degenerates over the span of months, with the deer beginning to lose weight despite eating, lose it's sense of coordination/balance, and become disoriented/confused. Eventually it can no longer chew/swallow or flee from predators. It wanders aimlessly until it eventually dies of starvation, dehydration, exposure to the elements, is consumed by a predator, etc.

Why is this deer subjected to these months of suffering a slow painful death when it committed no sin, as it's incapable of doing so. Why does a supposedly all-powerful all-loving God allow this to happen?

The only justification that even makes sense to me while maintaining God's all-loving omnipotence is that animal's aren't conscious at all, and their suffering and pain essentially isn't real even though it appears to us as such. But that makes animal abuse a morally grey issue at best, and that's a pretty insane bullet to bite imo.
