I restrict this discussion to moral evil, and specifically, moral evil leading to damnation. I will show that this remains an unsolved, and in fact, insoluble problem. While there exist logical solutions, they come at the cost of some other tenet of classical theism or Catholicism.
We assume the classical theistic God is omnipotent, omniscient, and omnibenevolent. Relevant to this discussion, God could actualize any logically and metaphysically possible world (omnipotence), He knows the actions of His creatures prior to their occurrence (omniscience), and He does not permit gratuitous (unnecessary) evil (omnibenevolence). We also assume the Christian God Who loves humanity to such an extent He sent His own Son that they might not perish but possess eternal life, but punishes the wicked with eternal damnation, should they choose to reject Him.
We use modal logic, with the distinction between “logically possible” worlds and “metaphysically possible” worlds. A logically possible world entails no contradictories (e.g. there are no squared circles) but it is not necessarily a metaphysically possible world, which is one that is actually possible given the nature of being, which we do not know everything about. (A three-horned horse is logically possible but may be metaphysically impossible.)
The “standard” answer is that, in order for there to exist moral good, there must also be moral evil. But logically there must only exist the potential for moral evil, not its actuality. Why did God not actualize a world in which all are in fact saved, even if it were logically possible for them not to be? There is no good answer. There are only in fact two logically possible answers, the “free will” defense and the “greater good” defense. I’ll first discuss the “free will” defense.
The “free will” defense argues that it is (epistemically) possible (that is, for all we know, it could be the case) that there are no metaphysically possible worlds in which all creatures always choose right, or a fortiori in which all are saved. (This assumes the Molinistic position of Divine scientia media and counterfactuals of freedom in order to preserve Divine omniscience.) This defense succeeds, as far as it goes. I cannot prove to metaphysical certainty, with our limited knowledge of metaphysics and philosophy, that there exists a metaphysically possible world in which all choose right and are saved.
But let’s consider the implications for a moment. In the first place, this is entirely unacceptable from a Catholic point of view; it’s more consonant with Calvinism (and the author of the “free will” defense, Alvin Plantinga, is I believe in some sort of Reformed denomination). Catholicism demands the metaphysical possibility of salvation for all and denies that Christ died for the elect only. And there are other philosophical problems.
Let’s (to simplify the issue, but it doesn’t really change anything) imagine God choosing between two worlds: one in which person A is saved and person B damned, and one in which person A is damned and person B saved. A world in which both A and B are saved is, we presume, metaphysically impossible. Let’s say God chooses the first one, with A saved, since He desires A saved (His motive in creating the world is His creatures’ good, being omnibenevolent as He is). B’s damnation therefore follows as a matter of metaphysical necessity, for given A’s salvation, there are no metaphysically possible worlds in which B is saved. It was metaphysically impossible for B to have chosen otherwise than he did, given the external circumstances. Now it is unjust to punish anyone for acting when it was impossible for him to act otherwise. (This is not, by the way, the same argument as claiming it is logically impossible to act otherwise than how God knows we will act. This is a classic modal fallacy of “if a, then necessarily a”; it is logically possible to so act, there are other logically possible worlds in which we act otherwise, our action is contingent, not necessary. Whereas in the case under discussion B’s actions are metaphysically necessary as there are no metaphysically possible worlds with the same circumstances where B acts otherwise.) Of course the same argument applies if God chooses to instantiate the second world for the sake of B’s salvation; A’s actions then follow by metaphysical necessity. Now to act from metaphysical necessity seems to me to be the antithesis of “free will” - it’s ironic that the “free will” defense should end up, in fact, denying “free will”. Of course some Protestants do, in fact, deny free will.
Now, it may be objected to this that I am assuming A’s (or B’s) salvation to be directly willed by God. Certainly, the argument is airtight if this is the case. There are no metaphysically possible worlds in which A’s or B’s salvation is directly willed by God and yet it doesn’t happen. And salvation must be willed by God, the source of all good in classical theism. But couldn’t God actualize a world in which either A or B would be saved, but then kind of let things “play out”? The answer is “no”, according to classical theism.
Classical theism demands infallible Divine foreknowledge of creatures’ actions in some way, although accounts differ as to exactly how this occurs. Thomist Divine causation was discussed above; according to Molinist scientia media, God knows how each creature would act in a given situation (brute-fact “counterfactuals of freedom”). God actualizes the external circumstances of the world, which means He must decide prior to its instantiation whether it is going to be A or B who is saved.
