If the issue of universal sovereignty is real, Satan's rule versus God's rule, and we all have to choose, there is a big advantage for Satan.
As imperfect humans, we are pre-disposed to sin. To say we have a choice or anywhere close to the same choice as perfect beings is ludicrous.
Your inclination is to sin (rebel). How can that be a fair opportunity? The sin is held against you, its not overlooked. You are then faced with the choice of keep sinning and die or submit to God and he will forgive you and heal you. Again is sin a choice? Are you choosing to be imperfect? Emphatically the answer is no.
There isn't any logical or fair way to settle such an issue, its not a level playing field. To gamble with the lives of living thinking feeling beings is disgusting. How could such an act endear either to a person. The picture paints us as nothing but pawns or poker chips in a celestial poker game in which one (God) can change the rules as often and in whatever way he wishes.
I can't buy in to the universal sovereignty issue as being legit.
