The first question is: “why did God create anything?”. If God is self-sufficient, then he does not need anything else. Whatever he “needed”, we have to assume (if God is logical) that the wolrd is precisely what he “needed” or “wanted”. He did not create a “perfect” world, because he ***did not want ***a perfect world. The world came out precisely as God wanted it: with all the horrors, misery, pain, suffering, rape, torture - as well as the good, love, decency etc.
And that puts God’s alleged “benevolence” into a very dubious light. A benevolent being simply does not intentionally create rapes, genocides, wars, plagues, etc… as long as the word “benevolent” has any meaning whatsoever.
Actually, the word ‘benevolent’ has plenty of meaning even in tha context, according to the Church’s view.
First, you’re confusing ‘allow’ with ‘intend’. Go to Plantinga: A benevolent being could (and reasonably, would) have plenty of reason to allow evil into the world on two grounds: One, the recognition that a world of utter ‘it will not get any better’ perfection may not be logically possible. You can always make a perfect world better by adding one more person. So to get anything done, you’re going to deal with a cutoff point (or with a world that can improve infinitely over time, in which case you can start from just about any degree of perfection.)
Two, certain goods aren’t available in a world without wars, rapes, plagues, genocides, disease, and otherwise. I’m not merely talking about ‘lessons learned from overcoming those things’, mind you - I’m talking about the existence of certain beings at all. You, for example. You as an individual (And myself, and everyone else) could not logically exist in a perfect world. Not only are you flawed, but your very existence in the world is dependent on a history of some flaws, and some evil. Ergo, remove the evil, remove the flaws, and you’re wiped out of existence in the process.
(You can reply ‘God could have made a perfect me, or at least a vastly better me!’, but it would have been ‘you’ only in the most mild and unimportant ways. Not your consciousness. Not your experience. Not your material. Not your history. Not your relationship. Not your universe. God could have made a better you in the same way God could have made you be Frank Sinatra: by removing everything it means to ‘be you’.)
The good that not only can, but must come from certain flaws and evils is abundant and easy to demonstrate. What’s more, if God does exist, then those evils would be utterly and ultimately temporary - every effect they have can be gotten past, every harm healed, and every resulting good nurtured.
In other words, for God to utterly disallow evil in a universe would be the sign of a God who was not omnibenevolent. He condemns imperfect, evil beings to nonexistence, even though any evil could be cured. He also condemns perfectly good beings who were victims to nonexistence as well. A man injured horribly due to war? Not worthy of existence - even though God could make his injury utterly temporary, and make the man himself better in every way through time and even nature. The soldier who injured that man unjustly, even gleefully? Not worthy of existence, even though he could repent, see the error of his ways, become a better person, take part in God’s plan, etc.
In other words, there’s no ‘dubious light’ of God’s benevolence in the Catholic (or really, most religious) understanding. It makes utter sense, to the point we should be grateful of what we see in this world - Leibniz’s “best of all possible worlds” and all that. Now, you can argue whether the religious understandings are ultimately accurate - if the dead will rise, and so on. Admittedly, even that tact has lost a whole lot of its power due to the advances of science; we now see inklings of what a world can be like in accordance with God’s plan. Many sick are healed, many more have real promises to be healed with advances, we see the results of the spread of many of Christ’s teachings to the world (even if they’re ebbing due to the results of secular influence, etc.)
The logical problem of evil fails. The evidential problem of evil takes a big hit. Reasons to doubt remain - in fact, reasons to doubt would (in my view) be present even in a world vastly better than this, because perfection is infinite in possibility. But reasons to be grateful for the world we live in, even as victims of evil, also make a strong showing. So the observation of a benevolent God allowing evil doesn’t do nearly what you seem to think it does. In fact, it largely works against the conclusion you’ve derived from it.
