Halcon: many simply cannot accept that he also has the final say.
This is an odd thing about gods, including Yahweh. They seem to disappoint those who know them directly.
If you were to know such a being unambiguously, there would be no question that he has the final say. He is a being of incomparable power. No one can possibly foil his plans, and no one can stand against him. There can't be any confusion about this.
And yet... so many of the people who knew him directly were unimpressed. If we go with the Christian narrative, the serpent is under the control of an angel who turned against god. This angel was able to turn the first humans against god. This angel -if the book of Revelations is to be believed- turned a third of the angels against this god. All of them knew that this action could only end in their destruction. But they were willing to turn against him anyway.
When I was a believer, I thought of god as the single most impressive and amazing individual I could possibly ever have the privilege of knowing. The idea that I might find him to be unimpressive or disappointing was simply unfathomable. And yet, so many of the people who met him were willing to turn on him, even knowing that this meant death (or worse, eternal torment).
The one constant with this being is his overwhelming power, and his willingness to use it to justify his actions. And even with that threat hanging over them, many beings have decided it is better to die and/or suffer than to live under his rule. What could they know about him that would lead them to behave in such a manner?
