...Mhalir is also confused about that. At the very least, he - finds it hard to imagine that any amount of torture could make him want to die. Not existing is awful. But, well, they've already noted Elves aren't psychologically quite like humans - they seem more uniform, for one, less variation than the Earth humans or Golarion humans he's observed, and...maybe their odd innocence and credulity makes them worse-affected by torture? They - don't seem very usable-by-Asmodeus, not that he has a great sense of that but based on his vague sense at least.
And Asmodeus wasn't maximizing for torture. He just - wanted to get people into a usable form, for His aims. A god who for some reason wanted to break people even more thoroughly than that - Mhalir can't really conceive of why, but presupposing it - could probably find something that even the people who were 'into that kind of thing' would be broken by.
<We need to know more. If Melkor did this and then the other gods let him go, then...> Fear, resignation, hardening resolve. <Then we have to do something.>
