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.
"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?"
