Specific kind of main hero (Jean Valjean style)

Hi! This is my first post here, so I hope I'm doing everything right!

I have a favourite type of character. I like heroes who were imprisoned, enslaved or brutally punished for a minor crime, or for no crime at all. I like it when they escape (or are released) and just want to live a good life, but their past still haunts them (either as a real-life threat or psychological trauma). I want them to remain a good person. I don't want a revenge-focused plot. I adore The Count of Monte Cristo, but that's not what I'm looking for here. (Although if we're just talking about 'origin stories', Edmond Dantès is the perfect example of this trope). Also, I don't mind a cynic as long as he's fundamentally good. I don't mind an antihero; I just don't want a villain.

Basically, the description may be convoluted, but I want Jean Valjean from Les Misérables. He's my absolutely perfect book hero, especially because he cares about the world (especially Cosette) and his conflict with Javert.

There was a character like this in The Shadow of the Wind. I read it years ago, but I still remember that he was a great character. I think he wasn't imprisoned, but he was interrogated very brutally. The idea is the same.

Another great example from the mainstream is Sirius Black from Harry Potter (mostly because after the Prisoner of Azkaban, his life's mission changed from 'kill Peter Pettigrew' to 'take care of Harry as much as possible given his circumstances').

I heard about someone in Joe Abercrombie's books, but having read a description, I don't think he is 'still good inside' because he is basically an executioner.

I prefer fantasy or historical fiction, but it doesn't have to be one of those genres. It could be a grand adventure or a slice-of-life story. Bonus points if the hero is psychologically accurate and still has some trauma from imprisonment.
