It’s always possible for a decent moral view to be self-effacing, because having true beliefs isn’t the most important thing in the world. If an evil demon said “Agree to moral brainwashing or I’ll torture everyone for eternity,” then you’d obviously better agree to the brainwashing.
What about the deontologist who says “I can’t agree to moral brainwashing because that would involve being complicit in an objective wrong”? I don’t see how this position reduces to or implies the belief that “having true beliefs [is] the most important thing in the world”.
Or by “decent moral view” did you mean “decent consequentialist moral view”?
Avoiding complicity (whatever that amounts to) also isn’t literally the most important thing in the world. Note that even most deontologists reject “though the heavens fall” absolutism.
