I think there are a few things you are missing:
1. Their thought process is most likely that any lawful good cleric, regard less of diety is an ally of Soon and his men and can't be trusted. Also
this comic shows that Girard think of the 12 gods of the south as a " glorified petting zoo", showing a disbelief of, or at least mistrust of gods in the first place so Durkon being a cleric of Thor obviously makes no difference.
2. They probably think they are. If they don't know that everyone is dead their thought process is most likely "I am died, A lawful cleric (obviously one of Soon's lackeys) is trying to raise me, if he does he will likely torture me or mind control me until I give him information on the gate, I better stay dead"
3. I am pretty sure that distrust can override curiousity in this case if they are this level of chaotic, also it has been shown that if someone is curious they don't need to be raised they can just go to
this demiplane a watch them, or just go down themselves.
