What Is The Ending Of Memoirs Of A Murderer Explained?

I can be blunt: the film wraps up by solving the immediate crime but leaves the moral questions wide open. In the climax of 'Memoir of a Murderer', the elderly former killer confronts the younger murderer and manages to stop him, appearing to save the vulnerable people he has befriended. On paper that reads like redemption — he finally uses his dark skills for protection rather than harm.

Yet the whole point is that he’s an unreliable narrator because of Alzheimer’s, so the emotional payoff is complicated. The ending alternates between concrete events (a confrontation and its aftermath) and fuzzier moments where memory and guilt overlay each other. The film ends less with a tidy moral judgment and more with the image of a man whose past and present are colliding; you’re left wondering whether forgiveness is possible when the man who seeks it can’t remember what he’s forgiven for. I left the theater thinking about how fragile identity is — and how a single act can’t erase everything that came before.

I watched 'Memoir of a Murderer' late one rainy night and the ending left me sitting on my couch for a long time, staring at the credits. On the surface the finale plays like a thriller’s catharsis: the older man with Alzheimer's, haunted by his past as a killer, squares off against the young murderer who has been terrorizing those around him. There’s a physical confrontation where the older man forces the truth into the open and neutralizes the immediate threat, and in that moment the movie seems to give him a kind of grim redemption — he protects the woman and child he’s come to care about, even if his memory is slipping away.

But what really made my skin crawl was the way the film refuses to give you clean closure. Because the protagonist is unreliable — his memories are fraying, and his old confessions as a serial killer still stain him — every act of heroism is shadowed by the possibility that he’s also the monster. The final scenes fold memory into present action: we see him writing or dealing with his memoirs, trying to fix a narrative about himself, but then there’s destruction and erasure too. The physical ending (the killing of the young murderer, the rescue, the fallout) is straightforward enough; the emotional ending is ambiguous. Is he a repentant protector finally doing the right thing, or does his presence simply continue a cycle of violence that he can no longer fully remember?

When I rewatch it, I notice little choices the director makes to deepen that ambiguity — close-ups of an object he keeps, repeated words he can’t anchor, and the way the camera sometimes lingers on faces instead of actions. Those moments suggest the film’s thesis: memory forms identity, but when memory dissolves, identity becomes a battlefield. So the ending isn’t just about who lives or dies, it’s about whether a person who cannot trust their own memories can ever be trusted by others — or by themselves. It left me feeling uneasy but oddly protective of him, like someone watching a person you care about lose pieces of themselves and trying to decide whether to forgive the parts you don’t understand.
