Sovereignty examined

A ruler who can rule if and only if all his subjects cannot make any free choice, vs a ruler who can rule a group of people who can choose to oppose him - which is more powerful, wiser, more skillful, more intelligent, greater - more capable? The one who can rule people that have free will.

If the only way the king can rule to accomplish the goal is to completely control everyone - that indicates a ruler who is not very capable; this is the way Calvinism portrays God.
