I never argued the problem for God in my post.
However there's certainly a case to be made for it.
A couple of philosophical arguments go like this:
1) Most (all?) evil done on Earth is done by humankind. Animals are just trying to survive for the most part, and eat each other to achieve this. But man is different. Man does most evil against man. In animals, usually their problems are predators, not each other. Man has the capacity for free will. But man chooses to do evil to their fellow human. God gave us free will. God doesn't interfere because He gave us that gift and gave us the ability to choose. Since God is not of material but exists outside of the material, God does not interact with us in a physical manner. Since God is not of the material, God will not descend to Earth to correct wrongs every time some human does something awful. And since all man sins and has the capacity for evil, it would be unlawful to do this. So God gives us a choice and humans do not live up to our, nor God's, standard. Let's be real. If human beings wanted to solve world hunger, we would. There's enough food and money in the world right now for us to achieve this. Why do we allow the poor to starve? Because man is broken. We could have had alternative fuel decades ago but man chose to stick with fossil fuels, why? Greed, power, fear of change. Because man is incomplete. Now we are facing climate change. Another man made evil, which will result in unstable weather patterns. Will we blame God for that too?
2. The harder answer. Evil exists because good exists. Without evil we would never have the capacity for good because we wouldn't know what evil even is. Man grows through struggle. It's hard to accept, but true. We've all been through hardship. Wars happen, but they allow actions of true goodness to shine in a world of darkness. Without evil how could we possibly achieve free will? If there isn't evil, good doesn't exist either. How could we choose? If we can't choose, we are just dolls and no different from animals. And where there's badness, there's often goodness. For example, we have natural disasters that harm people. It sucks that a tornado landed, but without thermodynamics the tornado wouldn't exist. Without thermodynamics we wouldn't have jet engines for example. But we also wouldn't have things that kill people like tornadoes. But I think all of us agree that tornadoes are worth keeping around if we get things like jet propulsion out of it. God likely sees it similarly. Because there is evil, there must also be an infinite good. And this infinite good is God. Essentially, evil allows human not only a choice, but also an opportunity to grow.
