Aspexia faced with this Carissa right now would be treating her at best as an ally of fragile convenience; she has little mercy for the followers of other gods and other ways.  A story which is purely about Irorian motives, compassionate motives, leads Aspexia to treat as an ally-of-convenience-at-best the expected-future-Carissa whom Aspexia expects to awaken after selling her soul and re-enhancing herself.

Aspexia probably does have some favor for the Carissa-who-was?  She has not decided that Carissa is all Irori and no Asmodeus, or Carissa would be treated differently, they would not bother trying to further corrupt her; the instructions from Hell imply that she has the potential to descend into corruption, and finally come to Hell without thought of other choices.  The story Aspexia is told shouldn't throw that away completely.
