1. Okay. Wasn't quite sure, but that's what we did.
2.
It could be more or less the same as a list of threat impulses:
* to own and sell people
* to denounce and overthrow
* to hunt and dominate
* to infect and poison
* to fight and wage war
* to turn people against each other
* to ruin things
Or it could be a bit more open-ended and evocative, but still give the MC a clear idea of what its motivation is, like the names of the threat types themselves (so, following the last list):
* Slaver trader
* Iconoclast (or Usurper, or Denouncer)
* Stalker (or Hunter)
* Poisoner (or Corrupter)
* Warrior (or Brawler, or maybe Punisher)
* Betrayer
* Despoiler (or Ruiner)
I didn't check to see if you already have a threat list for demons or other supernatural enemies, but you could just use that, or create this list and use it there as well.
What would I pick for Asmodeus? I think I want Asmodeus to tell me to ruin peoples' lives via subterfuge, so I would probably pick *to ruin things or *to infect and poison on the one list, and *Poisoner, *Betrayer, or *Despoiler on the other
