Kidding or not, the whole structure of this argument rests or falls on the idea of limits. I think from an epistemological point of view, the notion of what is implied in the idea of Satan’s battle on Mankind, if He were to become become God.However metaphysics has is one up on physics in this respect, the idea of aesthetic limits, the should versus the is, the agreeable aesthetic distance will reaffirm the advantages of the Faustian Man. The very early serpent simply could not do the necessary thinking that requires knowledge to reach the god. After the initial thought , the inspiration(that of the Word was begotten of) became the ether, through we actually can breathe. That is, the Holy Spirit, the Human consciousness. When these areas between the seeming limitless, and the actually limited will collide, at the day of reckoning, it will be as a dramatic demonstration to those whose grasp reality does not extend beyond the visual, but as subtly almost unnoticeable to those, who see limits as useful, natural reminders of what the Creation is all about.
As far as millions killed, well yes, the transhuman God will kindly re tribute with the two edged sword of the Karmic effects at that day of reckoning, which incidentally, has already began.
