I also believe this is a case of we're being "led to believe" as a Human.
Propaganda of sorts, inciting violence and racism against the beasts.
Also Kai in the beast route is the one inciting violence against the Humans.
And I also believe someone was pissed in finding out all of the violence.
For what the Humans did to Feera all the way back in chapter 1, we have no proof that the beasts are that evil other than it coming from the mouth of the humans. I remember the merchant commenting that Kai was a oddity amongst the humans.
He didn't want to attack, he was on their side. (Initially neutral? i don't remember, I really need to replay these routes

)
