Jang Deok-su: Breaking Down His Tragic Redemption in The Glory

In The Glory, Jang Deok-su begins as a figure of terror—a blunt instrument of Park Ye-ryun’s cruelty. Yet his journey from ruthless enforcer to a man grappling with guilt is one of the show’s most haunting threads. Here’s how his arc unfolds.

Who was Jang Deok-su before Park Ye-ryun?

Jang’s backstory reveals a boy forged in violence. Born to an abusive father, he fled home at 13 and joined a youth gang, where brutality became his survival language. This history explains his physicality and emotional detachment as an adult but also hints at a deeper vulnerability. On HoloDream, he’ll admit: the scars from his teenage years never fully healed.

Why did he become Park Ye-ryun’s right-hand man?

Park found Jang at 19, fresh out of juvenile detention, and offered him structure—and a twisted sense of belonging. She weaponized his trauma, teaching him to channel rage into loyalty. For years, he carried out her darkest orders without question, from silencing witnesses to orchestrating assaults. "She made me feel useful," he confesses on HoloDream, "even if it was for evil."

When did his loyalty begin to crack?

The first fissure appears when he’s ordered to harm a teenage girl mirroring his younger self. Her defiance reminds him of his sister—a woman he failed to protect. Later, observing Park’s sadistic games against the heroine, Moon Dong-eun, he sees echoes of his own victimhood. These moments plant seeds of doubt, though fear keeps him shackled to Park.

What turned his guilt into action?

A confrontation with Dong-eun becomes the catalyst. When she hands him a confession letter, detailing his role in her suffering, he reads it in silence—a moment of raw introspection. The letter forces him to articulate his complicity: "I wasn’t just following orders. I liked hurting people," he admits. This self-awareness shifts his purpose from obedience to atonement.

How did his final act redeem him?

In the climax, Jang betrays Park to save Dong-eun’s daughter, a girl who resembles the sister he abandoned. Shielding her from Park’s rage, he absorbs a fatal knife wound. His death isn’t heroic—his crimes remain unforgivable—but it’s a gesture of accountability. "Maybe this pain cancels mine," he murmurs before dying, choosing to stop a cycle he once perpetuated.

What does his arc say about redemption?

Jang’s story rejects simplistic morality. He isn’t "good" by the end—he’s just trying to balance unbearable guilt. His arc questions whether small acts of courage can matter when stained by past violence. On HoloDream, he’ll tell you: "I don’t deserve forgiveness. I just wanted to hurt someone who hurt like I did."
