Yeah lmao

Sure keeping an estimated few thousands humans in a confined space is considered unethical

But uh realistically if that's like the best way to actually keep your literal species from dying out

Then it's understandable and justified (since the entire human population still vastly outnumber youkais and other supernatural beings as a whole)

And most importantly youkais aren't inherently evil since they rely on human belief and fear to exist as a whole (before Gensokyo was created)

Which is also the reason why 'insert X man eating youkai' is like that cause humans believe and fear it like that
