Even after the paladins leave, Narikopolus doesn't really think about all of his wizards, or why none of them are assigned to stay with him. He doesn't think about a mass grave of hastily-buried buried unwilling mistresses. He doesn't think about someone initially responding to the new justice orders by simply moving his torture garden inside. He doesn't think about annual sacrifices to devils that he hasn't bothered to confirm have definitely, positively been discontinued. He doesn't think about horrible crimes committed after the amnesty. He doesn't think of men who despair of ever escaping hell, and don't see the point in trying. He doesn't think about men who are on their best behavior, and whose best behavior is still terrifyingly, shockingly stupid.
He doesn't think about it because these men, too, serve Iomedae. They serve Her just as surely as the ones with hidden copies of the Acts once served Asmodeus. No private exercise of conscience can change whose army they fight for, or the fact that without them, basic military operations would crumple.
But Asmodeus did not see it that way, and Narikopolus thinks without thinking that Iomedae will not, either. Let the Church or the Crown - old or new - know that the hearts of men are complicated, and they will inevitably come to burn them for their imperfections.
Narikopolus has never in his life stuck his neck out for anyone, politically. If Iomedae's forces see this ugliness and order him to send half his teleports to hell, then Narikopolus will swing the sword himself, if commanded. But he won't point them out. He won't help his masters tear their own forces to shreds. If he runs them well enough, they may not ask. And if Iomedae's gaze does fall on them - well, then he can honestly say that he hadn't been aware of any serious crimes committed for months and months, and hadn't been thinking about the old ones (though the habit of thought is really for casual mind reading, and not meant to stand up to truth spells). It was an error not to report them then, of course, but he was much, much worse at being an Iomedan then, and still trying to keep his lands from falling apart.
It's possible that if Narikopolus were thinking about it, his assessment might now be different. He might have call to reassess whether the Iomedans are as wasteful or stupid in their pursuit of purity as the Asmodeans. He might be able to consider whether he could tell them anything under confidentiality, and expect that anything he revealed wouldn't immediately run to the top of their command chain. He might be able to have any of these people talk to Iomedans, and get a better sense of what the rules are. He might be able to trade teleport favors, and let the Church make better use of his resources in achieving their shared goals - because even worse than decimated, the fact is that Menador still has more slack in its teleport operations than Lastwall does.
Maybe it would matter. Maybe it wouldn't. But Narikopolus isn't looking there, so it is not possible for him to see another way.
He does send letters, asking for specific lower-circle wizards to be brought down. He asks Llei to write a few, too, as Taggun Hold has more wizards than anywhere else in Menador. But he doesn't call his teleporters to stay any longer than needed to drop them all off.
