Getting to Know Eren in Attack on Titan

Eren Yeager is the main character in the anime Attack on Titan. Since childhood, Eren's life has been filled with tragedy. He witnessed his mother being eaten by a Titan when Maria's wall collapsed. From that moment, Eren vowed to destroy all Titans from the world.
Eren is known as an emotional, stubborn, and determined character. He joined the Scout Regiment to achieve freedom beyond the walls. However, as the story progresses, Eren begins to realize that the world isn't as simple as black and white.
After learning the truth about the outside world, the nation Marley, and the origins of the Titans, Eren's perspective changed completely.
Why did Eren become evil?

The question of why Eren became evil doesn't actually have a single answer. Eren's transformation occurred due to many interconnected factors.
Obsession with freedom
For Eren, freedom is everything. He hates anyone who takes away the freedom of others. Ironically, however, for the sake of his people's freedom (Eldia), Eren chose the path of extreme violence, even sacrificing millions of lives.
In his mind, the outside world was a threat that would one day destroy Paradis Island. Therefore, Eren felt he had no choice but to attack first.
Attack Titan's power load
The Attack Titan has the ability to see memories of the future. Eren knows what will happen, including the great destruction he himself will cause. This knowledge traps Eren in a fate he cannot escape.
He realized his actions were cruel, but he still did them because he felt everything was predetermined.
Trauma and loss
Since childhood, Eren has continually lost those closest to him. This trauma has shaped his personality, becoming increasingly cold and brutal. The world is a cruel place for Eren, so he feels he must become even crueler to survive.
In order to protect his friends
One of the biggest reasons why Eren became evil was because he wanted to protect Mikasa, Armin, and his friends. By making himself the world's enemy, Eren hopes that the people he loves can live safely after he dies.
Facts About Eren Yeager

He's more accurately described as an anti-hero. His goals are noble in his own eyes, even if his methods are flawed. - Eren realizes he is evil
