"Aroden was a man who became a god, and who believed that men ought to become gods. All of us, I think, ideally. As many of us as possible, definitely. He sponsored men to godhood, repeatedly; there are a dozen demigods who were once human men and women who he set on the road to godhood. Iomedae and Cayden and Norgorber, obviously, and Arazni, and Milani and Rixana and Dotara and Vadrus and Simaron and Doliu. He built the Starstone, of course. He was the god of the Empire. He was in favor of empires because he wanted to build Axis in this world, rather than tell everyone they have to wait for the next one. He wanted the world to be rich. He wanted every person to carry around pocket libraries and a thousand other things that I have witnessed and am not supposed to tell you about.
Iomedae was raised in the empire, at its height, and thought it was making two important mistakes. The first is that it was spending too much of its might on stupid things that did not matter. The second is that it kept doing Evils that everybody said must be done, that civilization could not function without, and she suspected that many of them were not necessary. She fought in the Crusade against Tar-Baphon, she became powerful, and she started trying to build a civilization that did not spend its might on stupid things that did not matter and that did the evils which were necessary but not any of the evils which were not. Lastwall was her attempt at that. And then she became a god, the god of prioritization - doing important things that affect lots of people, choosing your battles based on how much you win if you win them - and the god of the thesis that you do not actually have to run a civilization on torment and cruelty, that Good is not weak and that a civilization which protects its people and deals rightly by them will be stronger than one that doesn't.
She is very opposed to Asmodeus. She intended that civilization would someday be strong enough to fight Hell for all its souls. She is very opposed to the Abyss and to Abaddon, for about the same reason. She is not particularly interested in fighting random doers of random evils, except insofar as this is a good way to make things better. In Menador the church seems to have just attempted reconciling with everybody, presumably because they thought that was an easier way to make things better."
