Ah, so you are serious about this stuff. But your argument about God being incapable of granting free-will assumes that some 'other' entity has pre-destined his actions and not Himself. Not quite, if you agree God to be all-knowing and all powerful, you have to accept that His destiny is a result of His all-knowing quality, at which point His destiny and free-will becomes redundant and simply play of words. If you want to move forward I suggest you view the theodicy problem with-in Judeo-Christian view that relates to Hume's refutation of Aquinas/Anslem's cosmological argument. Else we simply go around and around without any sense.
