The Killer Inside Me (2010)

Plot:
Deputy Sheriff Lou Ford (Casey Affleck) is a pillar of the community in his small west Texas town, patient and apparently thoughtful. Some people think he is a little slow and maybe boring, but that he is nevertheless ordinary and dependable. Nobody knows about what Lou calls his "sickness": He is a violent sociopath with a taste for rape and murder. It nearly got him put away when he was younger, but his adopted brother took the fall for his crimes. But now the sickness that has been lying dormant for years is about to surface again and the consequences are brutal, devastating, and horrific.
