That business with ordering Carissa never to verbally request that he stop was really quite clever of him, now that his thoughts have run over it; Abrogail can't immediately see a way out of that as a checkmate against the way they were planning to lure him into Evil. Carissa should've looked sad and told him that an order like that would take the fun out for her, found some excuse to turn him down; as the Keltham expert it was her job to realize what he was really doing there; if Sevar is worried she's not being punished enough, she can repent her failures there.
