BBC's Peaky Blinders has that way of pulling people in, especially with the sharp suits, the slow-burning cigarettes, and the gritty soundtrack playing over a vintage backdrop. At first glance, it all feels polished, controlled, and almost glamorous. But it doesn’t take long before the layers start to peel. And what’s underneath isn’t pretty.
Beneath the cool facade, it’s a world full of betrayal, blood, and quiet breakdowns. And at the center of it all is Tommy Shelby, who is smart, calculating, and impossible to ignore. But also dangerous in ways that don’t always involve a gun. Peaky Blinders doesn’t let anyone off easy, especially not its main character.
The moment when everything turns
There’s one moment, one decision, that stands out among all the brutal things he’s done in Peaky Blinders, not because it was loud or flashy, but because it cut deeper. It didn’t just hurt enemies or strangers. It tore through the people closest to him, especially the ones still standing by his side after everything.

It wasn’t about violence. It was a choice
It wasn’t a gunshot or a bombing. It was a betrayal, plain and brutal. Tommy handed over his own family in season 3, not to save them or even to save himself. It was all part of a larger game, a strategy involving politics, the Russians, and whatever new threat was at his door. He thought he could handle it. He thought it was worth it.
The worst Peaky Blinders betrayal came from within
Arthur, already unraveling, was left in chains. John didn’t even know what he was caught in. And Polly, so proud, so fierce, just stared. Like something in her had snapped. And Tommy, he just stood there. Cold. Still. Like that was the only move left.
Some people say killing Michael in the end was worse. Maybe. But at least that came with confrontation, with the final line being crossed. The betrayal in season 3 was quiet. Clinical. It was Tommy choosing power over people, over his own blood.

The scene no one forgets
This scene lingers, constituted by Arthur's screams, Polly’s silence, and Tommy's complete detachment. Maybe that’s how he survives. But for the ones who loved him, who trusted him, it was a line too far.
And it didn’t stop there
This betrayal wasn’t a one-time thing. He kept doing it, with Lizzie, with Finn, and even with his own son. He loves them, maybe. But he doesn’t know how to show it without controlling or without hurting first. He believes pain is a form of protection. The Peaky Blinders cycle just keeps repeating.
Cillian Murphy brings it all to the surface
The performance behind all of this is haunting. It’s not just in the voice or the walk. It’s in the eyes, the way Tommy speaks is without ever really saying what he feels, the way he pulls Arthur in and keeps Ada at arm’s length. There’s always distance, even when he’s right there.

A slow but sharp unraveling in Peaky Blinders
The show doesn’t rush that descent. It builds it layer by layer, season by season. At first, Tommy seems like a survivor. A soldier. But then the cracks start showing. The insomnia. The guilt. The obsession. The way he tries to carry everything but ends up destroying whatever he touches. Peaky Blinders explores this downfall without ever really offering relief.
And yet, it’s hard to look away
Maybe that’s why it’s so compelling - knowing he’s going to fall again, but hoping something changes, hoping that maybe this time he makes it right. He tries, in his own way. But he never fully escapes the spiral.
What comes next in the Peaky Blinders universe
The series may have wrapped, but there’s still talk of a movie. Rumors of a final story. Maybe we’ll see an older Tommy, who would be a man facing his limits, his past. Maybe he’ll fix something. Or maybe not. Maybe it’ll end the way it began, with him trying to outplay a game that never really had rules.
And still, people stay
Even with all the betrayal, the violence, the cold decisions, it’s that moment in season 3 that stays. The one that showed who he had become. Or maybe who he always was. Because while enemies came and went, the deepest wound came from within.
And that’s why, of all the things Tommy Shelby ever did in Peaky Blinders, the worst was turning on the ones who gave him something to come back to. Because even after all of it, people kept watching, not because he was good, but because he was real, flawed, and somehow, still standing.
