@Crowsfoot fair enough. Still kiiinda necro for me since the topic is so old. But necro can be a good thing. In the forums I moderated over the years I was always fond of necros since they are often useful. But we are not here to talk about undead but about demons. So to the topic of celestial demons and good vs. evil: Me being someone who is both new to the Warhammer lore, and dislikes crapsack worlds in general, you will probably not be too surprised that I dislike the old Warhammer lore. 40K is even worse than Fantasy IMO. There are literally no good guys. The ones qualifiying as "good" for some people in that world are T'au. And as a D&D fan I strongly disagree. In fact I disagree so strongly I just went full Khrushchev, took off one of my shoes and pounded the table with it. My coworkers think I am insane. I don't know much about T'au, but I know enough to say that T'au are not generally good guys. They are maybe the good guys compared to some other factions, but that's like saying (sorry for the real world comparison) Saudi-Arabia is a free country because the people there are less oppressed than people in North Korea. In fact North Korea would probably pass as the good guys in the 40K world. T'au are lawful evil, I have no doubt about that. They are an expansionist empire, and it seems their definition of good means that they rule and everyone follows their rules. Now back to demons: When I started to read AoS lore and how Seraphon work, and when reading the part about celestial demons I immediately thought of D&D and regular celestials there. I'd say Seraphon are much less evil than their fantasy counterparts from what I can see. No lobotomized slaves and such stuff. In Fantasy it seems they were pretty much lawful neutral. The "lawful" part comes from the extreme order they seemingly embodied, with the Great Plan and so on. They weren't evil in D&D terms because that would imply selfishness, and they weren't really selfish. They did thing because they had to be done, the Slann being huge powerful biological computers computing the best solutions to thge problems that were preventing them from fulfilling the plan. and if someone was in the way he had to move or die. That's neither good nor evil. Now with AoS things changed I think. They did shift quite a bit towards good. But I still struggle to call them "Lawful Good" because they do not act altruistic. They fight Chaos, because that's what they always have done, because it was their original purpose. They cannot stop so what they do is not "good", it just happens to be helpful to the good guys. ...which brings me to Stormcast Eternals. From what I know that Sigmar guy is a pretty OK guy, I'd say we have some Lawful Good Celestial army there. btw: In some newer D&D publications "Outsider" is the general term anyway (for anything coming from another plane of existence than the mortal plane, such as the gods' and demigods' planes or the elemental planes), with Demons and Devils being evil Outsiders and Angels and Devas and a few others being good (or evil or neutral depending on their gods) Outsiders, and Elementals being neutral Outsiders. I see the Warhammer term of "Demon" more akin to that than to something related to good or evil, while the Warhammer term of "Celestial" is only used for good ones, just as it is used in D&D for good Outsiders. I perceive the Warhammer AoS world is still much more Order vs. Chaos than good vs. evil. The Destruction faction is fighting the Chaos faction, but that's more for survival than anything else, Orruks and Grots fight the Order guys or even each other just as enthusiastically it seems. I'd say "Chaotic Neutral" is a pretty good D&D alignment label for them. The Death faction is clearly more lawful than both Chaos and Destruction, so they are closer to the Order side. They might still side for pretty much anyone because with wars and everyone dying (except Chaos demons, Seraphon and Stormcast) and such they are in a win-win situation I guess? Lawful evil to Lawful neutral I think. The Death guys are a bit more active and more inhomogenous than undead in most fantasy settings. The other question of this thread is also interesting for me. Could a chaos demon be good? I don't know. I tend to say no. His deeds may be perceived good by some, but from what I read it is pretty much impossible for those guys to even have altruistic feelings, so if he does something perceived as "good" it is either some kind of trick, or a side effect he probably doesn't even know or care about. It is more of the nature of Chaos (randomness) than something on the good-evil axis.
