He’s the most hated hero in anime. Or maybe the most loved villain. Honestly, it depends on which season of Attack on Titan you’re watching. Eren Jaeger didn't just change; he imploded. Most fans remember him as that screaming kid who wanted to kill every Titan. By the end, he was the guy trampling the world into dust.
But here’s the thing. People keep arguing over whether he was "controlled" by the future or if he just turned into a monster. It’s neither. And it's both.
Eren is a mess of contradictions. He wanted freedom more than anything. Yet, he became a slave to a future he already saw. If you think he was just some strategic genius or a pure-evil genocidal maniac, you’re missing the point of what Hajime Isayama actually wrote.

The "Slave to Freedom" Paradox
It sounds cool, right? "I am free." Eren says it constantly in the final arc. But he’s lying. Mostly to himself.
The Attack Titan has this weird, time-bending power. It sees the memories of future inheritors. When Eren touched Historia’s hand at the end of Season 3, his brain basically got fried by the future. He didn't just see "a" future; he saw his future.
Why he couldn't just stop
A lot of people ask: "Why didn't he just choose not to do the Rumbling?"
He tried.
In the manga and anime, we see him looking for other ways. He went to Marley. He listened to the peace talks. He hoped—really, desperately hoped—that the future he saw was wrong. But every time he took a step, the world reacted exactly how his memories said it would.
It’s like being in a car where you can see the crash coming from a mile away, but your hands are glued to the steering wheel. Or worse, you’re the one choosing to turn the wheel because the alternative feels even more terrifying. For Eren, the alternative was the total wipeout of his friends and his home.
The Disappointment of the "Outside World"
This is the part that gets lost in all the "Yeagerist" vs. "Alliance" debates. Isayama dropped a huge bombshell in an interview with the New York Times. He mentioned that Eren’s dream wasn't just about saving Paradis.
It was about the book.
Remember Armin’s book? The one with the flaming water and lands of ice? Eren didn't just want to see those things. He wanted a world that matched the book—a world that was empty. A clean slate.

When he crossed the sea and found out that the outside world was just full of more people, more walls, and more hatred... he was disappointed. He says it straight to Ramzi, the little refugee boy: "When I learned that humanity lived beyond the walls, I was so disappointed."
That is dark. It’s not just "I have to kill them to save my friends." It’s "I want to wipe it all away because it didn't look like my dream."
Breaking Down the Rumbling Logic
Let’s look at the numbers. They’re horrifying.
- 80% of humanity: Flattened.
- The Goal: Make his friends into heroes who saved the world from him.
- The Result: A temporary peace that eventually crumbled anyway.
Was it worth it? Most characters in the show say no. Even Eren, in his final talk with Armin in the "Paths," admits he’s an idiot who got hold of too much power. He isn't a 4D chess player with a perfect plan. He’s a traumatized 19-year-old with the power of a god and the emotional stability of a glass vase.
He killed billions because he couldn't find another way, and because deep down, a part of him wanted to do it. That’s the nuance. He hated himself for it, but he still kept moving forward.
What Fans Get Wrong About the Ending
If you hang out on Reddit or Twitter, you've seen the "Eren is Back" memes. Some people wanted him to win completely. Others hated that he cried about Mikasa in the final chapter.

The "Simp" Argument
"He ruined the character by making him cry over a girl!"
Actually, that moment was the most "Eren" he’d been in years. Since the time-skip, he’d been wearing this mask of a cold, stoic leader. But underneath? He was still that same emotional, pathetic kid from Shiganshina. Seeing him break down and admit he didn't want to die, and that he wanted Mikasa to love him, wasn't a "retcon." It was the mask slipping.
The "No Choice" Myth
Eren had a choice, but his nature wouldn't let him pick anything else. He is the personification of the "Will to Power" mixed with a "Fatalistic" nightmare. He did what he did because he is who he is.
The Philosophy of the Scarf
Everything in Attack on Titan comes back to the scarf. It represents the "cruel but beautiful" world.
Eren gave Mikasa that scarf after murdering two people to save her when they were kids. That was always Eren. He was always a "monster" who would do anything for the people he loved. We just cheered for it in Season 1 because he was killing "monsters." When the monsters turned out to be people, our perspective changed. Eren’s didn't.
How to Actually Understand Eren's Legacy
If you’re trying to make sense of the ending or his motivations, stop looking for a "hero" or a "villain." Think of him as a tragedy of environment and power.
- Read the Manga Chapters 130 and 131 again. These are the most honest looks inside his head. They show his guilt and his weird, twisted sense of freedom.
- Watch the final OVA episodes. They add a lot of context to how he felt about his friends.
- Accept the "Paths" logic. Time isn't linear for the Founder. Eren was experiencing the past, present, and future all at once. His mind was literally shattered.
Eren Jaeger didn't save the world. He saved his friends—for a little while. He ended the Titan curse, but he couldn't end human nature. In the end, the tree grew back. The cycle started over. He was just a boy who wanted to see the ocean and ended up drowning the world to get there.
Next time you rewatch the series, look at his eyes during the ocean scene at the end of Season 3. He isn't looking at the water. He’s looking at the horizon, already seeing the fire he’s about to start.
Actionable Insight: If you're writing your own stories or analyzing characters, use Eren as a case study in Internal vs. External Conflict. His biggest enemy was never Marley; it was his own inability to accept a world that wasn't "free" by his impossible standards.
