I don't know of any stories of transformation that are about real life people and events because most of the films or literature we see are about superhero or anthropomorphic transformation, they are fake and after seeing or reading them, we are left unconvinced. This film shows that a mind and soul has the potential for any gamut of quality no matter where it's been. It's what any religion wants to convey, inner freedom. What I loved most about this method is that these prisoners had to face the internal horrors of what they had done, and sit with their emotions, ultimately reconciling in some form with their past and experiencing true repentance. This type of rehabilitation not only frees the victimizer, but the victim as well, because that inner self resolution on the part of the victimizer is most what the victim or their families want and probably the only thing that would allow them to forgive to some degree and move on.
