Pay attention to the lore, the beastmen and disfavored are mortal enemies. There can be no negotiation.
So much for being a fatebinder. You supported the disfavored once, so now their mortal enemies are also your mortal enemies. No more need for any judgements.
You're enemies at war with each other. They have no reason to trust you unless you consistently disobey orders, proving you're on their side. Even then there's a psychopath option where you can choose to attack them when they offer an alliance.
But you cannot. You don't even get the option to prove yourself. Don't let that first rebel go, no questions asked? Irredeemable mortal enemies forever. You do let a single rebel leader go? This changes things entirely!
To me this is a juvenile, simplistic worldview.
I guess we will just have to agree to disagree
