All I recall is the man's trauma over his murdered brother was used as a plot device to tell us how hard poor Fordola "The Butcher" had it--and Raubahn's dialogue implied the other Crania Lupi must've been free to go despite their deeds, too? We probably should have checked if Ungust had a sick mother back in ARR, I guess.
The writers' preoccupation with handwaving atrocities and ignoring the victims is really offputting.
Experiment notes in Ktisis Hyperboreia describe what sound a lot like the Lupin--intelligent, bipedal, wolfish creatures that were created and then deleted for "improvements" because they were not capable of speech, which is a pretty grotesque take all its own.
My "really ugly" comment was made in regards to a neighboring thread's spin of E-S' body count:

Emet-Selch himself says it: "I don't consider you to be alive, ergo i'm not commiting murder". He's just mending the broken souls and healing the world, in his view.
--which is pretty much done and dusted if the Lupin implication is correct. Personally, I'm sick of all the excuses made for his atrocities in general, both from his fanbase and the writers, and have been since ShB was launched.
