I’m looking for a film where a person was abused as a child, and he became an adult to protect children from violence. I think he’s a boxer. At the end of the film, he sees how the father punishes the daughter, and at night falls into their house, where he kills the father of the girl (I remember that the father has a nosebleed). A mother shoots the murderer of a revolver (as far as I remember, Nagant) and wounded him in the arm. Then he goes to prison and is killed with a knife by prisoners (before his death he sees scenes from his childhood and life).
Saw this the film somewhere in 2010-2011. I can not find the description, can someone help?
