An argument defeating the "Free Will defense" of the problem of evil.
OK, contradictory semantic constructions exist - but they have no referent in the actual world. How's this?:
1. An object that is describable as a logical contradiction is metaphysically impossible. (e.g. square circles are metaphysically impossible)
2. If x exists then x is metaphysically possible (converse of 1)
3. Omnipotence entails the ability to directly create any contingent entity whose existence is metaphysically possible.
4. There exist contingent free-willed souls in heaven who do not sin (e.g. the departed souls of faithful Christians). (Christian doctrine).
5. Therefore God's omnipotence entails the ability to directly create free-willed beings that do not sin.
6. Therefore God could have created a world of free-willed beings who do not sin
7. In this world, evil befalls the innocent due to the sinful acts of free-willed individuals
8. God created this world instead of a world of free willed beings that do not sin.
9. Therefore God chose a world with needless pain and suffering.
10. Therefore God is not omnibenevolent.
