So, I just realized - the 40k intro says that the emperor is the master of mankind... by 'the will of the gods', amongst other things. But - which gods? The only gods notably present in 40k are the chaos gods.
I mean, maybe I'm reading too much into it, but it struck me as strange. Was the intro originally supposed to suggest that the chaos gods want to keep the emperor in place for their own ends? :/
Well, from a certain point of view, Chaos
needs an opposition like the Imperium or it might possibly cease to exist. Although many of the adaptations and evolutions of Imperial Society are/were intended or arose through selective pressure to combat Chaotic influence, it's hard to argue that as an end-product there would be many other configurations of a state that
could possibly be more repressive, despotic, stagnant, neglectful, warmongering and genocidal than the Imperium has ended up being.
In being so, the Imperium ironically is a nigh perfect breeding ground for ever more Chaos, simply because life or even
chance of survival is so bad for so many people that they see little other option than the Ruinous Powers to improve their lives or even see another day with their loved ones.
It's telling that eternal slavery and damnation to the whims of uncaring Lovecraftian horror-devils who prey on and perpetuate the worst of reality and life, who demand ever more atrocities, irrespective of innocence or reason, ever more absolute defilement of one's self and everyone and everything one once held dear - even taking into account that people often are at first ignorant of the true extent of the evil they are joining and spreading or the totality of themselves and everything and everyone they know they would be sacrificing (including whatever reasons likely initially compelled them to seek Chaos in the first place), only realising the extent of their mistake, if they ever do, once they've been cognitively corrupted and twisted beyond recognition - that Chaos
still finds not only desperate followers but
willing eager acolytes, amongst those who if taught nothing else by bitter collective experience and zealous official properganda
are taught to fear, distrust and hate the Archenemy, repeatly and uninterrupted, for
millennia.
Consorting with Chaos never ends well, yet time and time again people turn to it, because their alternatives, the material reality the Imperium in no small part presents them with, are so terrible (at least from their individual and communal material perspectives, unaware of the more eschatological risks Chaos poses to themselves and reality).
Now, one can also argue that this is a biased perspective of the Chaos gods (assuming they are the primary or only gods referred to by the intro), who don't have
all the power to manipulate the situation, but it's hard to argue they haven't benefited immensely from the Imperium as it came to be (and perhaps moreso what it
failed to be) both under the Emperor guidance and in the intermittent ten millennia since his internment on the Golden Throne.
