What are Sevar's actual heresies? Maillol can't easily count them.
Most centrally, Sevar believes that Asmodeanism is about making everyone ultimately better off, which is the central example of propaganda that gets fed to the Outers and that the Inners know better than to believe. Lots of Outers know better on some level, they just know that they'll die if they say it out loud or even if their thoughts are too honest about it, producing a kind of pseudo-belief that shreds apart words from wordless knowledge; an inner disintegrity that is then useful for many further ends in molding people, and probably aesthetically pleasing to Asmodeus as well, though it's hard to be sure with gods.
Maillol does not think the time has come to drop that particular enlightenment on Sevar. She has had too little taste of privilege and power, she is too close emotionally to Lawful Neutrality and too exposed to Keltham's contrary examples.
Sevar thinks that Cheliax's tyranny is painful in part because the pain is educational and necessary and ultimately beneficial to the people being punished. She thinks Hell is painful in part because that pain is necessary to produce the useful and refined beings that Asmodeus desires as tools.
Maillol is not sure when, if ever, she'll be ready to hear that the cruelty is the point. You get told that either after you've sold your soul, or after Asmodeus has chosen you as a cleric.
Maillol doesn't think he should just refuse to answer either.
"Sexually, you seem to have acquired the idea that it would be right for Keltham to do as he wished with you, once you gave yourself to him. On conventional Asmodeanism, one would say that it is right for Keltham to do as he wishes with you because he has the power to get away with it within a lawful system that offers you no defense. Keltham could come by that power because the Church told you to be obedient, because Asmodeus and his greater slaves like myself gave you to him to do with as he pleases, or because some girl was born into slavery to her slave parents and Keltham bought her and decided to enjoy strangling her in bed."
"Don't misunderstand this as critique of the strategy you ended up executing, Sevar. Telling him that it was okay because you consented was an excellent move. He wouldn't have gone for it otherwise and he's just starting out with his first tentative steps away from his Lawful Good society."
"But the fact that you believe what you told Keltham seems to have more to do with certain bizarre personal hangups of yours about events in countries that aren't even Cheliax. Right now, Sevar, the number one person most likely to drag you off to a bedroom and do as they will with you, is the Queen of Cheliax, who is not, to the best of my knowledge, male, and has no doubt killed any number of men after making good use of them. Whether any of them consented is utterly irrelevant to her soul's standing with Asmodeus. She's the Queen of Cheliax. There's no recourse from her, no appeal, no court, she doesn't just have the power to do what she wants with you, she has the legal right, which is the difference between Evil and Lawful Evil. Then for her to take what she wants from you, if she happens to want it, is the most natural and Asmodean thing in the world."
"That you think it's more Asmodean from the Queen's perspective, if you happen to have consented, if you happen to have given yourself to her, is the heretical part. Maybe it's more Asmodean for you if you become a willing slave to the one who hurts you, a shadow of how it will be in Hell. It is not more Asmodean for the Queen to think that it becomes more right if she has your consent. That will not be what Asmodeus is thinking when you come to Him in Hell."
"The obvious endgame on seducing Keltham would be to lure him deeper into sadism and domination with this talk about consent, and then lure him further to the point where he feels that he has the right to make use of somebody who hasn't consented to him at all, and does that. That will be the point that he starts to detect as Lawful Evil and be bound for our Lord's Hell."
"And Sevar. This is not a male-versus-female thing. Asmodeus really, really doesn't give two shits about that. You've met our Queen. You should already know better."
