By the Devil's Hands (2009)
Plot: Joseph is a man struggling with a deep internal darkness and a history of mental instability. After a series of traumatic events, he becomes convinced that he is being directly manipulated by demonic forces. This obsession leads him down a violent path as he begins to believe that the only way to satisfy these "voices" is through blood sacrifice. The film is a gritty, low-budget character study that blurs the lines between a traditional slasher and a psychological breakdown, focusing on Joseph’s descent into madness as he terrorizes those around him, believing he is doing the Devil's work.
