the point is do they even think it is betraying him? because the fact is that its ordered by someone more powerful then the mc and they are brainwashed into thinking that whatever the shah (idk the name the one in power) is doing he is right, and I'm not sure what you mean by pretending to be a devoted servant, to his belief he is being the most devoted he believes he can be, by sacrificing himself thats literally the culture

okay why are yall blaming all the servants they dont have power and shit and also the culture is different so they think differently da heck the only person at fault rn is the guy (i forgot his name) in charge of the ritual and shah amon
