Why not make A.S. benevolent instead of arrogant?

I understand that Aurelion Sol is definitely in a position to be smug, but I've felt since his teaser that his character might be better off if his fatal flaw was kindness rather than hubris. Aurelion has affection for every star in the universe, and should presumably have affection for the universe in general. He could just as easily act as a humble, benevolent, djinn-like figure to lesser beings- vastly more powerful, yet willing to serve. Were this the case, his backstory- accepting a crown from humans, and being held hostage by it- would still make sense. Although incredibly strong, he is pure enough to be easily fooled and corrupted by human beings.

Sidenote: This makes his character fall more in line with IRL mythological elements while actually subverting the stereotype of a dragon. In most myths, when a giant or an ogre or a dragon- any powerful being- is manipulated into doing something against its will by a human's appeal to its hubris, the monster is the evil bad guy and the human is the clever hero. In his lore as it is now, our subconscious impulse is still to root for the humans who outwit the dragon with their clever crown. This somewhat dulls the emotional impact of a very tragic turn of events. If Aurelion Sol were pure- sort of an archetypical unicorn rather than an archetypical dragon, if you will- I think the idea of a creator deity being enslaved by his own creations would hit the audience way harder.

And, in the present, I think his character would have been more morally intriguing. As a benevolent god of creation, Aurelion would presumably be horrified at the idea of destroying his precious stars (this comes across in his lore already, in fact). The purpose of the crown, then, should be made more abstract- the stars are not disappearing from the night sky as punishment for Aurelion's disobedience, but rather as a result of Aurelion's direct actions. Looking at modern myth, he would serve (in his crowned state) as a sort of Galactus - Silver Surfer fusion. Galactus terrifies us because of classic cosmic horror elements; the Silver Surfer intrigues us as a sympathetic character forced to serve destruction. Marvel has done great sci-fi mythmaking, but these two are definitely their best. The creator is forced to destroy his own creation- against his will, no less. If there is any way to make puny mortals feel very sorry for God, this is it. A final reason to justify this personality change is clarity. I personally think that a benevolent Aurelion Sol is more appealing and perhaps more complex than an arrogant Aurelion Sol, but the biggest advantage here is the extent to which it simplifies his motivation and his backstory in general. Watch: Aurelion Sol is a benevolent demigod that made all of the stars in the universe. A long time ago, humans tricked Aurelion Sol into accepting a gift, a crown, that let them control his power. Since then, the once-loving dragon has been forced to destroy his own creations against his will. But the crown's power over him is waning. Aurelion Sol has returned to Mt. Targon to attempt to overthrow his masters and save what remains of the cosmos- from himself.

I find that very compelling. As is, it feels like Aurelion Sol is only trying to overpower his crown so that he can be a ruthless dick on his own terms. Maybe more realistic, but the stakes don't seem high and neither side of the conflict grabs my attention.
