fiends can be redeemed like how angels can fall, what about stench kows

stench kows are fiends according to mordenkainen presents: monsters of the multiverse, could a stench kow be redeemed in the correct circumstances and what would that do to them?

Um.. it's an unaligned fiend? Someone didn't think about what they were doing.

I think the Kows might simply be native, so you can’t really redeem them since that’s where they are naturally meant to be.

I think calling them Fiends is fair since they're native to the Lower Planes, but yeah they're also just wildlife rather than something of enough sapience/cognizance to have an alignment.

The only way to redeem them is to turn them into stenchburgers.
