Alushinyrra is awful, of course. What else could anyone possibly have expected? (Yes, this is Regill's surprised face. Not at the Abyss being terrible, but that anyone would possibly say so in a tone hinting at surprise or indignation.) Obviously Evil without discipline is terrible. (So is Good, for that matter, but the failure modes are different.) When Hell hurts someone - which it does, Regill knows that perfectly well, you needn't put on your surprised face - it's with some purpose in mind. Not so much to make them follow orders - even the demons do sometimes manage that much - but to make them better order-followers; to inculcate the habit of discipline and obedience, to put the whip into a soul, not a back.
This place? It hurts people from sheer slovenly lack of capacity to do anything else.
Savalemekh's alleged "plan", for example. A plot spanning decades, corrupting generations of crusaders, hurting the mongrels terribly, and for what? If Asmodeus had done something of the sort - if Regill had! - then He would have gotten some strong and loyal followers or cat's-paws out of it! What did Savamelekh get? Debuffing Lann for long enough that the killing blow was landed by one of his companions; and Wenduag. (To be fair, Wenduag did indeed have little kitty-cat paws. Too bad about the utter insanity.)
Feh. Regill can't wait for Asmodeus to conquer the universe and put these entities to some sort of useful work. Paving stones, probably, that's about their speed; but better that, than lying about pretending to be beggars.
