Eren Yeager: Hero or Villain? The Truth Behind His Evolution

Spoilers Alert

Eren Yeager is one of the most complex and controversial protagonists in anime history. Introduced as a determined young boy who dreams of freedom, his journey in Attack on Titan takes a dramatic turn as he transforms into a figure that is both admired and feared. Over the course of the series, Eren evolves from a passionate soldier fighting against the Titans to a mastermind who wages war against the entire world.

This transformation raises a crucial question: is Eren a hero or a villain? At the beginning of the story, he is portrayed as a courageous individual, willing to do whatever it takes to protect humanity. However, as his actions become more extreme, many begin to see him as a ruthless destroyer rather than a savior. His role in shaping the fate of the world blurs the line between good and evil, making it difficult to categorize him in a traditional sense.

The goal of this article is to analyze Eren’s evolution, exploring his motivations, choices, and the consequences of his actions. By examining his journey, we will determine whether he can truly be defined as a hero, a villain, or something beyond.

Eren’s Journey: From Innocence to Determination

Before becoming a symbol of war and destruction, Eren Yeager was just an ordinary boy with a dream—to see the world beyond the walls. Growing up in Shiganshina, he longed for freedom, inspired by stories of the vast world outside. He despised the idea of being trapped and believed that humanity deserved to reclaim what was lost. His curiosity and rebellious nature made him question the world’s restrictions, setting the foundation for his strong-willed personality.

However, Eren’s innocence was shattered when the Colossal Titan broke through Wall Maria, allowing Titans to invade his home. He was forced to witness the brutal death of his mother, devoured right before his eyes while he was powerless to save her. This moment became the defining catalyst for his hatred toward Titans and his unwavering resolve to eliminate them. From that point on, his childhood dreams of exploration were replaced by a burning desire for revenge.

Eren joined the Survey Corps, determined to gain the strength needed to destroy every Titan. His initial motivation was simple: wipe out the enemy and protect humanity. However, as he uncovered the truth behind the Titans and the world beyond the walls, his perspective began to shift. What started as a straightforward mission of revenge slowly transformed into something much more complex, leading him down a path that would challenge his beliefs and force him to make impossible choices.

Eren as a Symbol of Freedom

From the very beginning, Eren Yeager’s life revolves around the idea of freedom. He despises the walls that confine humanity, believing that true life can only be experienced beyond them. As he grows, this belief intensifies, shaping his every action. Unlike others who accept their fate, Eren refuses to be a prisoner of circumstance. His definition of freedom becomes an obsession—one that leads him down a path of both heroism and destruction.

Eren’s pursuit of freedom can be compared to other key characters in Attack on Titan. Armin Arlert, his closest friend, also dreams of the outside world, but he values peace and diplomacy. Zeke Yeager, on the other hand, believes that true freedom comes from ending Eldian suffering through sterilization. Reiner Braun struggles between his duty to Marley and his guilt, never truly free from his past actions. Unlike them, Eren is willing to take absolute control of his fate, even if it means sacrificing others.

This raises an important moral dilemma: to what extent does the pursuit of freedom justify the means used to achieve it? Eren believes that freedom is worth any cost, leading him to initiate the Rumbling, which wipes out most of humanity. While some view him as a savior, ensuring Eldia’s survival, others see him as a villain, committing genocide in the name of his ideals. His actions force us to question: is freedom truly freedom if it comes at such a high price?

The Shift: Eren’s Transformation in the Marley Arc

The Marley Arc marks a turning point in Eren Yeager’s transformation, showing a completely different version of the character we once knew. No longer the impulsive, hot-headed boy driven by emotion, Eren becomes a cold and calculating warrior, capable of manipulating both enemies and allies to achieve his goals. His attack on Liberio, where he slaughters civilians and military leaders alike, shocks the world and redefines the perception of his character.

This shift in Eren’s personality is evident in how he operates. As a child, he was reckless and emotional, acting on impulse rather than strategy. However, in Marley, he infiltrates enemy territory, living undercover for years, carefully planning his next move. His ability to deceive even his closest friends, including Armin and Mikasa, demonstrates his newfound willingness to act alone, making decisions based purely on what he sees as necessary rather than what is morally right.

Beyond his actions, Eren’s speeches in Marley reveal a darker philosophy. He speaks of freedom, but his version of it now involves the complete destruction of his enemies. His words, once filled with hope for the future, now carry a terrifying certainty—he is prepared to do whatever it takes, regardless of the consequences.

This raises the question: Is Eren still the hero of the story, or has he become its villain? His transformation from a vengeful soldier to a merciless force of destruction blurs the lines between heroism and villainy, making it difficult to define him in simple terms.

The Rumbling: Genocide as a Means to an End

The Rumbling is the ultimate execution of Eren Yeager’s plan, a devastating event that redefines him as either the world’s savior or its greatest villain. Upon gaining full control of the Founding Titan, Eren unleashes the Colossal Titans within the walls, sending them on a path of destruction to wipe out most of humanity beyond Paradis. His justification? To ensure the survival of his people and grant them absolute freedom by eliminating their enemies once and for all.

This decision presents an extreme ethical dilemma: is genocide ever a “necessary evil”, or is it the ultimate act of a true villain? From Eren’s perspective, he sees no alternative—if he does nothing, the world will eventually annihilate the Eldians. To him, the only way to achieve true freedom for Paradis is to eliminate all external threats, even if it means committing an atrocity on an unimaginable scale. His unwavering resolve and belief in his mission make him a terrifying force, one that cannot be reasoned with.

However, his actions divide not only the world but also his closest allies. Armin, Mikasa, Jean, and others, who once fought by his side, now find themselves questioning their loyalty to their childhood friend. While some still sympathize with Eren’s pain and motivations, they cannot justify his method of achieving peace. This internal conflict between loyalty and morality creates one of the most heartbreaking aspects of the story—can they betray the person they once loved, or must they stand against him to protect what remains of humanity?

In the end, the Rumbling cements Eren’s place in history as a figure of both tragedy and terror. Whether he is seen as a hero or a villain depends on perspective, but one thing is undeniable—his choices reshape the world forever, leaving behind a legacy drenched in both sacrifice and bloodshed.

Eren Through the Eyes of Others

Eren Yeager’s legacy is not defined solely by his actions but also by how others perceive him. To some, he is a hero, a martyr, or even a monster—a character whose identity shifts depending on the perspective.

For Armin and Mikasa, Eren is far more than just the Founding Titan or the leader of the Rumbling. Armin, despite opposing Eren’s actions, still believes there was a reason behind them—perhaps an attempt to make Paradis strong enough to survive. He sees Eren as a tragic figure, someone who carried the world’s burden alone. Mikasa, on the other hand, struggles with her emotions, torn between love and duty. In the end, she is the one forced to end his life, proving that despite everything, she still cherishes the boy he once was.

From Marley’s perspective, Eren is nothing but a devil, the embodiment of Eldian destruction. His actions confirm their worst fears: the island’s demons will destroy the world if given the chance. To the rest of humanity, he is the greatest threat they ever faced, a name that will live on in terror.

After his death, the world remains deeply divided. Some honor Eren as the man who saved Paradis, while others curse him as the monster who nearly ended civilization. His impact is undeniable—whether as a savior or a villain, Eren Yeager changed history forever.

Hero, Villain, or Antihero? Analyzing Eren’s Legacy

Eren Yeager is one of the most complex and polarizing characters in anime history. Like Light Yagami (Death Note), Lelouch vi Britannia (Code Geass), and Thanos (Marvel), his actions blur the lines between hero, villain, and antihero. Each of these figures justifies extreme actions for what they believe is a greater cause—whether it’s justice, revolution, or survival. Eren, in particular, embodies this moral ambiguity to an even greater extent.

Throughout Attack on Titan, the series challenges the idea of absolute morality. Is Eren a hero, sacrificing himself to secure Paradis’ survival? A villain, committing genocide on an unprecedented scale? Or an antihero, someone whose actions are justified within his own worldview but remain morally questionable? The story doesn’t provide a definitive answer, leaving the interpretation up to the audience.

Eren’s legacy extends far beyond the world of Attack on Titan. To some fans, he represents freedom and determination, a character who fights against fate and oppression. To others, he is a tragic warning of how obsession and revenge can lead to destruction. His journey resonates deeply, making him one of the most debated protagonists in modern anime.

Ultimately, Eren Yeager is not just a hero or a villain—he is something beyond those labels, a character whose complexity and contradictions will be analyzed for years to come.

Conclusion

Eren Yeager’s journey in Attack on Titan is a perfect blend of heroism and villainy, making him one of the most debated characters in anime history. From an innocent boy who dreamed of freedom to a ruthless figure who triggered mass destruction, his evolution challenges the audience to question morality, justice, and the true cost of freedom.

The debate over Eren’s true nature has no simple answer. He is both a savior and a destroyer, a victim of a cruel world and a perpetrator of unimaginable violence. His actions were driven by unwavering conviction, but does that make him a hero? His sacrifices saved Paradis, yet the cost was genocide—does that make him a villain?

Perhaps the truth lies beyond these labels. In the end, Eren was simply human—flawed, determined, and willing to go to any lengths for what he believed in. And that is what makes his story unforgettable.
