A forewarning, since i am biased towards Teanam here. I'll try to provide context needed to make sense of this thread for those who have not read the story. sorry for spoilers if you have not read it.
EDIT: Dont let this post taint your view of the story before you have read it, it only talks about the MC's interaction with the Humans in the story, and covers maybe a dozen chapters out of nearly 400 chapters.
The MC, has had ALL of their traits, boosted by a flat multiplier, including anger, etc. these raise the ceiling and lower the floor for how happy, angry etc you can get.
Humans, have had propaganda shoved down their throat for a long time about how they are the strongest on the planet. Humans there are the same as us, just their physical strength to their name, with none of the technology we use for force multiplication. in a world where the more magic you have, the stronger you are in all senses.
The first meeting between the two in chapter 15 showcased ALL you need to know about the average humans in the story. Teanam has said their are outliers of the human race which are not like them though, but its rare, and only when they grow up outside of human cities, or are old enough to have explored outside their land.
the humans hunting a Kow (its just a slightly stronger cow) say this when one of them gets the sharp end of the horn "Y-You lowly beast! How dare you hurt one of us superior humans!".
the MC steps in to save their lives in chapter 16, after which, they attempt to force her into "service". if you get what i mean without spelling it out. She walks away, the threshold for her anger not yet reached, and rationalizes away that it was that group that was the outliers, so heads for a human city to make sure she was correct.
Arriving at the gate, the guards call her companion and talking wolf a "lowly beast".
Realizing that she needed an ID to get in to their "beautiful and perfect city" and getting called a "filthy girl". when she asked for ways into the city without an ID, they tried to force her into brothel work.
being pushed past the threshold for her anger, she barely managed to NOT flatten the entire city, which she is easily strong enough to do.
After that, we don't meet humans at all, they are only mentioned every now and then, until the humans decided to start a war to steal a bunch of beast-men children as slaves. which, as you might know, would make damn near everyone angry, let alone someone whose anger goes nuclear.
What happens next (chapter 100) is a cake walk, where she used "dark magic" to brainwash the human army into leaving beast-men alone, where they would be terrified of them on sight. which works. admittedly, it would have been more humane to kill them all, but its both war and you have a stupidly angry tiger upset they want to take children. Yes, that is the single darkest point in the story. but it only lasts 4 chapters and humans stay out of the story until the redemption bit begins for them.
The only point that could even remotely be called "brutally torturing a prisoner of war" would be after said war (chapter 114), when the MC ran in to a human that the main human army had left behind because they were injured. She threw a stone at him gently, to wake him up from being practically unconscious due to having been out in the wilderness for 3 days with no water, a black and purple leg, and little to no food. the stone which accidentally hit said broken leg. (That might have been on purpose, and I'm seeing the MC in a better light than i should, but it said accidental, she just didn't care that she did hit it) after he has woken up and stabilized from the sudden hit on his very painful leg, they just talked, and MC asked questions about the human race, gave him some water, healed his leg, and left.
As far as I'm concerned, the human wasn't a prisoner of war, wasn't tortured, even if he was interrogated, and it certainly wasn't brutal.
Humans themselves have shown up in not even ten total chapters, most of it is just talking about them. Every time they have been in a chapter, they have been living garbage. the Overseer, AKA gods, but they don't like that name, say that MOST of the humans are like what the MC interacted with, with very few exceptions.
It is true that for what the story is most of the time, which is fluffy, the humans were a huge outlier. But to have it entrench into your mind so much that for months and months are you read the story, you KEEP going on about it, constantly dragging the story into the dirt because you personally don't agree with it, when the author just wants you to leave them and their readers alone, is confusing as hell.
