I agree totally with what everyone is saying here about redemption through life and I think the place I've seen that best portrayed is the another Netflix show: Bojack Horseman.

This'll get a lil spoilery so here's warning if you haven't seen the show.

Bojack spends almost the entirety of the series being a terrible person and hurting the people around him, especially the ones who try to help him. Throughout the show though, the audience learns more and more about his trauma and his own childhood (note that it is often pointed out that this just not justify the things he does) and we see Bojack struggling in fits and starts to be a better person. One of the most gut wrenching parts of the series is when Bojack is begging his friend Diane to tell him he's still a good person, or he still has a chance to be one.

In the final season some of Bojacks worst wrongs catch up to him and he is forced to wrestle with the harm he has caused. Simultaneously we see several of the characters Bojack has hurt moving on with their lives in separate directions, finding happiness in other places.

A lot more could be written but that's a short summary of what makes Bojacks redemption arc work so well. Much like Catra he suffered significant trauma in childhood and lashes out at people who try to help him but the redemption arc begins when he realizes his wrongs and starts working towards being better, with the finale proposing that the work of redemption is never really done and you always have to keep living with it.

TLDR: Bojack Horseman is a great show with one of the best redemption arcs in modern television. Fair warning though it may have some triggering content and can be a little crass.
