Other interpretation is that that's statement's under the assumption that if the critter wasn't, it would, y'know, actually do something about all the shitty shit what shits upon existence. Maybe not be a genocidal jackass, as a bonus, I'unno.
Personally, if my knowledge of the world included a means to prevent shit like stillborns, SIDS, etc., so forth, so on, I would probably get right on that. Maybe not order mass rape, commit mass murder and infanticide, allow all the torturous atrocities mankind gets up to, stuff like that. Try to come off as something besides a homicidal egoistic psychopath. The little things.
Some sort of lack of agency goes a long way towards... well, not exactly excusing that, but at least making it understandable. Plays nicely into the atemporal thing that's often posited regarding the critter's nature, too. All that happens has already been done by that way of looking at things, and the critter's a slave, in the sense of being unable to do anything about it, to actions already committed. The omniscience is just part of the decision making that's already occurred, even if it's in the relative (to mankind) future.
Dunno if that's actually particularly in line with the biblical depictions, though. Iirc, there's bits where the critter is stated as changing its mind (the second covenant bit would be a pretty big one, imo), and the omniscience thing is... arguable, as is exactly what that entails even if that is how the all-knowing stuff tracks. Critter gets played up a lot in the fanfiction, really...
