The thing is, the Alraune is practically a demon, while the demon merchant is practically not a demon. The Alraune came into existence because of Kas, was instructed by Kas, and basically only knew to do what Kas told her to. This resulted in her essentially being a mass-rape demon, despite not technically being a demon, and she violates many innocents. Farrah, the previously catfolk demon, is not evil. She has not committed any evil act, no rape, no murder, no theft. She has no desire to take souls, as she has no use for them, and she has no reason or want to bring corruption. She was raped by Kasyrra while she was traveling on a road, her soul forcefully taken from her while she was in a daze. She shows no hostility to the Champ even though the Champ's first reaction is to pull a weapon on her, unlike the Alraune who's first interaction was to attack the party, and when the Champ makes clear that they don't want Farrah's presence, she flees, rather than attacking. I'd guess that even if the Champ tried to attack, she'd just flee immediately.I'm not entirely sure who you're referring to here, I'm guessing either the Alraune or Azzy's queen (I forget her name, have only done her quest once.) The Alraune choice is particularly odd since she IS corrupt, but not a demon, yet you're given the option to kill her. Yet, later on when the full-fledged demon kitty merchant shows up at the fort, your options are "fuck yes," "only if you behave," or "no fuck off." This is probably another multi-writer issue, but the PC's mercy is rather inconsistent it seems.
Basically, the Alraune acts like a demon, committing heinous acts on mass numbers of innocents, while Farrah does not act like a demon, she's just an innocent victim who got caught in the crossfire. She has no victims of her own, and she holds no desire to, as she mostly just wants to continue trading like she used to. The Alraune can be seen as too far gone, a danger with an extreme likelihood of bringing further harm should she be left alive. Farrah is not an extreme danger, and she's not too far gone, despite the demonhood.
