I think something that really messes with me is Bigby Wolf was never born a human, his parents were literally a wolf and the wind. It wasn't until Snow sliced him with that lycanthropy stained knife that he gained a human form, all this to say he's an animal learning humanity.
I think despite his shortcomings and instincts he's doing a real good job too. He's got more empathy and care than some of the 'human' fables in game, and he's still treated like shit. He deserves the clean slate that they were all promised when they moved to fabletown and he never gets it. (Obviously I understand some of the hostile behavior from the other fables if you play an aggressive Bigby and Kill a tweedle, rip off Gren's arm, beat up a tweedle / woodsman at interoggation etc etc, but they treat him almost identically if you play a pacifist Bigby route)
Tldr: to quote Faith / Nerissa: he's not as bad as everyone says he is my man deserves better
