God cannot create Beings with Free Will
Let's suppose Bob has free will under Classical theism.
ie God created Bob with free will.
It's Monday morning and Bob can either choose to drink coffee or tea as he likes both. Bob freely chooses tea.
But, that's merely a contingent fact. Bob could've chosen coffee instead.
God is Causally Responsible for creating this particular Possible world where Bob chooses tea this Monday. God could've actually Actualized a possible world where Bob chose coffee instead of tea. God isn't merely an Omniscient Observer who's causally isolated from us, but is the Necessary Being who sufficiently explains every contingency. God could've made a world where every single Contingent fact is the same EXCEPT Bob choosing tea and making that to a coffee.
So from God's pov, God can never create Free agents. Because God could easily create a possible world where the "free" agent does X instead of Y.
You don't need to agree with the Metaphysical modality presented by the Contingency argument for this to work. You could be a theist like Richard Swinburne who thinks God is also a contingenct being (Brute). This argument still holds as God is Causally Responsible for every other Contingent facts except himself (since he's Brute).
