Ari is patrolling the streets of scenic Vancouver! Well, actually he's just going to visit Peter, but he's keeping an eye out for monsters along the way. It's a nice night, monsters like ruining that kind of thing. The streets are more or less deserted, it being 2:00 AM on a Tuesday. Ari whistles cheerfully.
[...We vote no on helping her unless she can be calmed down on the ant blood business. And would like more details on the evil.]
She pauses. And he betrayed me. Which is unforgivable.
She takes a sip. "And my revenge on Anduriel is non-negotiable. If you attempt to stop me, you will fail."
"I mean, they don't have souls. There might be a couple who mutated in such a way that their essential purpose isn't horrible, but I wouldn't bank on it. And without souls they can't change or be cured or whatever you'd do instead of killing them."
"Well, you've got one. I don't, but my essential purpose is complex enough that it doesn't matter for practical purposes. Souls are what let you mortals just sort of- exist, without being anything. You're not defined by the need to make shoes or eat people or murder lost children or something, you just sort of... happen. Anything without a soul does what it was made to do, and everything else is secondary."
"Yeah, a lifetime of agonizing doubt without the clarity afforded by their essential natures sounds so much better than painlessly ceasing to exist. They aren't made to be- fluttering about in the wind like you are. If I was a nixie and you excised my desire to drown wayward children I'd take a nail gun to my jugular."
"It'd be like instantly going from two dimensions to three and not having any idea how to deal with them. And feeling crippling guilt about all of the horrible things you've done over three thousand years of absolute knowledge that what you were doing was right. And 90% of your friends are dead. Oblivion is a fucking cakewalk."
His audience would like to double-check that none of these people have friends not slated for destruction who might miss them. Elsewise the low-conflict solution of pulling the obliterated creatures from Downside and applying creativity without going through God seems good to them.
"...I guess it's possible? But the things I'd be destroying are the things that are essentially purpose-made for killing anything with a soul. You can check the species for mutations that'd make them less evil, if you like, I'll delay this until you're comfortable letting me stop them from devouring more innocents with every passing moment."
She concentrates for a few minutes, sorting through all of the malevolent soulless looking for those who should be spared.
At length, she looks up. "All I found was a vampire who thinks he's some kind of superhero and a cabal of demons who deliver groceries in exchange for pixie dust instead of murdering people. And there's a bunch of them who fit themselves into human society, and some of them have 'friends', but they're just saving them up to eat later. Can I make with the cleansing now?"
