There's a movie I watched years and years ago, but I forgot almost everything about it except for one scene.

A murderer killed either the daughter or the wife of a character narrating this scene, who describe how the murderer genuinely repented in prison and became religious. After he was released from prison, the victim's father began to stalk and follow him everywhere he went, until the murderer couldn't take it anymore and slit his own throat with a straight razor after seeing the father stare at him through the window outside his apartment, thinking that if he damns himself to hell, it'd be the only place the father won't be able to follow him to. However, the father ends up taking out a cutthroat razor of his own and slits his own throat to try and follow him into hell. Back in the present, we find out this character was the father who survived his suicide attempt and wears a scarf of some kind around his neck to hide his neck scar.

Does anyone remember what movie I'm talking about?
