Part of why the idea of a higher power is not liked is because...well, if you haven't kept track of the alpha, such a entity hardly exists. The few rules of the game, such as no one side losing completely, and score, are not explictly explained for why they are necessary. They just are. Same for woes. They just are.
The idea of chaos, that it just is there, gels for this reason.
The idea of some higher power, appearing only when you are playing a certain way, doesn't gel so well. It's too isolated. If such a theme was more pervasive as a whole it would make more sense.
But right now, things are left vague, allowing players to fill in the blanks, which is a good thing. On the positive media thread, a recent review said the scoring and the not dying thing is a result of you, as creator, wants the game as a source of entertainment so you want humans to be entertaining both short term and long term, mean humans fight but don't completely win. There are a hundred potential interpretations as to why these rules exist, and that in the end makes them more palatable in the long run.
Chaos is vague, so you can do a similar thing. For me, they are offerings that keep you in power. For another, it could be for another reason like providing sacrifices to prevent greater evils. Chaos is vague, so either could work.
The idea of some arbitrary thing causing this just doesn't gel with the otherwise vague ideas, so it is not liked as much.
