Peaky Blinders: The Immortal Man reveals a twist that sparked a fierce fan debate: Tommy intentionally killed Arthur. Was it a logical conclusion or a character betrayal? Explore the deep psychological meaning behind the brothers’ final encounter.
The release of Peaky Blinders: The Immortal Man was always destined to be a lightning rod for controversy. Four years after the conclusion of the sixth season, the expectations surrounding the return of these iconic characters were far too high to avoid a fierce debate. Steven Knight, the series’ creator, was certainly not timid in his narrative choices: the plot twists and shifts in perspective are so radical that many fans have begun to question whether these versions of the characters still hold continuity with the ones we knew in the series.
Beyond the “impossible” returns and a finale steeped in the classical myth of patricide, the film’s most polarizing moment is a staggering confession. In a room where no one can hear him, Tommy Shelby speaks to his sister Ada as she lies dead before him. He reveals a dark truth: in 1938—two years before the film’s timeline begins—Tommy was the one who killed their brother, Arthur.
Arthur is physically absent from the movie, yet his spectral presence weighs like a mountain on Tommy’s soul. This confession, however, shifts the nature of his pain and ignites a desperate question: Why did Tommy kill Arthur? What is the profound psychological and existential motive behind such a tragic and devastating choice?
The Immortal Man: The Weight of Infinite Guilt
The story of Peaky Blinders: The Immortal Man unfolds in 1940. The Nazi regime is relentlessly bombing the United Kingdom—the last bastion of armed resistance against Hitler’s total victory. In this crumbling world, Ada Thorne remains a Member of Parliament and the final voice of reason within the Shelby family. Meanwhile, the family’s criminal enterprises are now led by Tommy’s son, Duke, who—as Ada sharply observes—is “running the Peaky Blinders like it’s 1919 all over again.”
Amidst this chaos, Thomas Shelby is a devastated man. He is the ghost of the gangster he once was, fighting “a personal war inside his own head.” He has retreated into a life of total isolation, accompanied only by the loyal Johnny Doggs—the last man left in his service. As the world drifts toward oblivion and a nation prays for divine intervention, Tommy, the only man who could truly change the tide if he chose to, is busy writing a damn book.
This is the stage for the film: a slow, haunting portrait of a man who is “immortal” against his will. Tommy is a shadow of his former self, constantly attempting to become someone else in a world that denies him any chance of rebirth. Thomas Shelby is destined for immortality despite having been “dead” since the Great War. He isn’t even allowed to disappear; history keeps knocking on his door.
The Nazi threat is personified by John Beckett, who seeks an alliance with Duke Shelby, hoping to use the Peaky Blinders as foot soldiers in the struggle against the UK. This ruthless pact, however, demands an immediate and staggering price: Beckett orders Duke to kill his aunt, Ada. In this moment, Duke discovers he still possesses a family conscience—a sense of dignity that reminds him he is a man defined by significant bonds, even with those by whom he felt abandoned.
But Duke’s hesitation isn’t enough. Ada is murdered by Beckett just as Tommy is making his way back to the streets of Birmingham. Upon his arrival, Tommy is forced to face the brutal reality: he is the last of the “Old Shelbys” left alive. In this context, the confession whispered to his sister’s corpse becomes more than a secret—it becomes an obligatory act of mourning.
The Shadow That Devours Everything: Tommy, Arthur, the Confession and the Fan Outcry
In the cold, silent corridor of the mortuary, Tommy is alone. The lifeless body of Ada lies before him, forcing him to reckon with his own identity as a Shelby. His mind drifts back to Arthur’s death. Earlier in the film, Tommy had recounted his brother’s end to Kaulo, describing it as a tragic accident fueled by Arthur’s long-standing drug addiction. In that version of events, Tommy revealed a detail that would later serve as a crucial key to the truth: “He started to believe I was the devil.”
But to his dead sister, Tommy cannot lie. In a staggering confession, he reveals that Arthur’s death was no accident: he killed him with his own hands. It is a moment that demands we replay his words in our minds:
“I killed our brother Arthur. It wasn’t an accident. It wasn’t an act of mercy. I killed him because I was full of booze and rage. And I had a moment when I could’ve spared him.
I killed my own brother. ’cause I wanted to be free of him.”
It is a shock to the system. This revelation has become the epicenter of the most heated fan debates since the film’s release. For many, a Tommy Shelby capable of murdering his brother is a betrayal of the character established over six seasons—a man who consistently sacrificed everything to save Arthur from his own demons and from himself. For others, however, the act is not so implausible; it is seen as the ultimate, albeit horrific, manifestation of Tommy’s cold, calculating nature.
That murder, however, was the moment “the door in my head blew open,” as Tommy himself explains. The guilt is both authentic and destructive, blurring the very identity of Thomas Shelby. He no longer knows how to define himself. The shadow of his own capacity for evil has swallowed everything, and his self-imposed exile has not been enough to achieve the rebirth he so desperately craves.
The Sacrifice of Cain: Why Did Tommy Kill Arthur?
Thomas Shelby was a man forever in flight from himself. For years, he meticulously crafted an image of a respectable statesman, yet the very nature of his empire made true respectability an impossibility. Arthur was the dark mirror that reflected Tommy’s true self; it was Arthur who stained his hands with the foulest crimes so that Tommy could continue to chase the chimera of dignity.
The realization—whether real or imagined—that Arthur saw Tommy as “the devil” is deeply introspective: the devil is, in reality, how Tommy views himself. Tommy used Arthur his entire life, transforming him into the ruthless instrument of his own darkened soul. Years later, as Tommy fought to leave his past behind, Arthur’s mere presence remained the undeniable proof of Tommy’s fractured spirit.
Tommy felt he had manipulated Arthur from the start, holding himself responsible for the demons that tortured his brother daily. Simultaneously, Arthur acted as an anchor, a weight that prevented Tommy from moving forward; one look into his brother’s eyes was probably enough to force the agonizing truth of who Tommy really was back to the surface. Ultimately, fueled by alcohol and a flash of rage over Arthur’s actions that night, Tommy strangled his brother with his own hands. It wasn’t just a murder, and it wasn’t an accident: it was suicide by proxy.
The Dorian Gray of Birmingham
By eliminating Arthur, Tommy sought to end the man who had absorbed all of his own wickedness. Like a flesh-and-blood Portrait of Dorian Gray, Arthur was the living image of Tommy’s spiritual corruption. In killing him, Tommy sacrificed “Cain” in the desperate, misguided hope of being reborn as “Abel.”
It was, of course, a grand illusion. Instead of liberating him from the grip of the past, the weight of fratricide opened a crater within his psyche—a void that would become his new identity. The “door in his head” blew open to reveal a bottomless abyss. In that darkness, Tommy realized he was exactly what Arthur had seen in his final moments: The Devil.
Did Some Good Come From This Bad?
The final promise Tommy makes to his dead sister is that “from this bad will come something good.” Tommy’s endgame is to ally with his son, Duke, to avenge Ada’s murder. The trust the father places in the son becomes a final test of humanity—one that Duke ultimately passes. He refuses to betray his blood, joining his father in the final confrontation to strike down John Beckett.
Kaulo’s prophecy was that Tommy would find peace, one way or another, and in the end, it comes to pass. Before his demise, Beckett fires two shots into Tommy’s abdomen. Tommy falls into the arms of his son, Duke—powerless, an empty shell of the man he once was, held tight by the energetic future of the family.
It is inevitable: it falls to Duke to perform the “act of mercy” that no one in the Shelby family ever had the courage to enact. Thomas Shelby dies in the warm embrace of a son with whom he never shared a true bond of love. But perhaps there was never room for human warmth in the life of Thomas Shelby. He dies as a defeated devil, finally taking with him the curse that, in one way or another, had defined the lives of all his siblings.
