This is YOUR definition...
Available to what?
Available as an option
By your own definition the “character” and/or “nature” determines the “set of options” available! In your MODEL, what are the options available to... if not to the “Will”?
I sense an error of Circular Reasoning coming!
And I sense you still avoid addressing what you have been asked to addreds from the the beginning
And you ignored the question of God's freedom
Did God have a huge gap in his decision processes ?
Was creation determined for him ?
Did he have no other option ?
Was God's decision determined or just random chance ?
Is it impossible for God to create a creature with a limited amount of his capability
Why is it you cannot/willnot defend you determined /random chance model ?
