I'm about to pour a lot of brain processing power into an isekai that, although seems a bit promising due to its comedic nature, may just be another junk.
So, uh... I am actually a believer in real world, but that's only because there's only ONE God (or at least according to many religions, their religion is the correct one). If there are multiple Gods and with their own hierarchy, I can't help but to smell the same political bullcrap. Since Gods in this story, I assume even the 'kind' ones, are actually honor and potentially power hungry, it's not far too outrageous to think of them as humans, but with wide knowledge and mighty supernatural power. It's pretty much another form of intelligent life. And when there are multiple intelligent lives, there prone to be egos which cause conflict of interest that tend to be solved with violence. Some are smart, and some are just muscle brain. Smart ones, even though they might be weaker, most likely emerge as victors due to its intelligence. Just like how humans are weaker than most animals, but emerge as the ruler of the world. It's very possible each has their own interest and that every second, the role of good and evil can be turned. Heck, even the name, 'evil gods' may actually be a made-up terms designed to fear-monger humans (believers).
Not saying that it is 100% the case, but it's a reasonable possibility.
