Anyway, it occurs to me that Soul Trapped Dremora/Aureals/Mazken seem to wiggle free from the grasp of the ideal masters.
I mention this because I was trying to map out a list of practices that a moral PC might accept for who is fair game to soul trap. I place Necromancers and Vampire Masters in that list because they eagerly do the same to you. (Purchased filled soul gems would not be acceptable. Looted ones are.) Mostly I was debating whether to add daedra to the list.
So really, two issues:
[1] When can a moral PC justify trapping/using soul gems? I don't give a rancid dingo's kidney about what YOU do, I just want thoughts on what is morally justified.
[2] Do you aggree that the daedric races wiggle free from the ideal masters?
