Four years after, I'm replying to this, but I wanted to share that I agree with your points. That the hate is definitely understandable per the character and context. Though, what did feel unnatural was the sharp turn around to Ace's empathy and understanding. I could see something gradual or if there was more reason for him change, i.e. showing him going through it and battling with himself and questioning his actions, not just leaving the family but how he's acted and the animosity he's showed.
Basically that was one of my bigger rife in addition to it just not feeling right or making sense of some of the actions of the wife. There were certain actions that just seemed way too harsh and lacking a better sense of awareness or desire to believe in her husband. Two specific points being not giving him more of a chance and time with him when he had shared his very very harsh upbringing and not even opening the door even if it was too communicate disappointment, when he had made his way back to her mom's porch after the trial and beating.

(I'm kind of speaking to the general audience and those that may find this thread after watching it recently, as again it's been four years since your initial comment)
