There is a limit. Hook never atoned for anything so his whole “redemption” is a joke in my opinion (as well as Regina’s and Zelena’s for all those who are ready to jump and call me a bitter shipper or whatever). I, personally, would find it hard to forgive someone who deliberately killed one of my family members even after they supposedly “changed”.
Well at least you are consistent. But I mean, with this logic, no one could ever get redeemed bc you would never forgive them. So why even try to change? And you can’t say these characters haven’t tried to change. They have, and for the most part, they have all succeeded. Zelena isn’t really wicked anymore. She has found love in her daughter Robyn. Regina isn’t evil anymore. She has found love within her family and Henry. Hook isn’t a bad pirate anymore. He has found love with Emma. I think all three, especially Regina, have atoned. Regina spent whole two seasons with everyone hating her and not trusting her. She has lost Robin. Hook still has his gf’s dad calling him a dirty pirate even though he’s been a good person for the last couple seasons. Idk. I just feel bad for Hook bc most have accepted that he has changed and accepted he was a bad pirate that killed people in the past. And now, nothing has changed. He was still a bad pirate, but now we find out one random guy in the woods happened to be Charming’s dad bc of course it was, and now everyone isn’t going to trust him again. It’s just too bad. It’s not like he did something in the present that was awful. Then that would be regressing and I wouldn’t feel bad at all. This is different.
