Zeke Yeager, otherwise known as the Beast Titan or just The Beast, is the main antagonist of the Attack on Titan series.
It was because of his future-seeing abilities that most of the story transpired the way it did, which makes Eren seem even eviler than how he was initially presented. Eren wasn't always an evil character, but there are plenty of hints sprinkled throughout the series regarding what he was destined to become.
But with the final chapter of the series bidding Eren a final goodbye, he was able to have a conversation with Armin in which he was able to explain why he became such a villain in the first place. It's because he wanted to make the Survey Corps seem like heroes to the rest of humanity.

Eren is afraid of his beliefs being shattered. His entire life he has been driven by this idea that is so clearly morally correct, but it is becoming not clear anymore. He has many moments of weakness because he is wavering in these beliefs, as any normal human would.
Eren's goal is to eliminate the entire world except for Paradis, but keeping his fellow Paradisans alive is also extremely important to him, especially his close friends.

Due to the time jump and how much more he learned about the world, Eren's personality greatly changed. This new side of Eren was nothing like what fans would have expected him to become.
Because Eren wanted to end the titans which requires his friends to kill him but if they does that they can't go back to Paradis. So they needs a place. Also without any enemy paradis will get into civil war like they did before.
How Eren treats his friends is one of the most interesting aspects of his character. He always makes it clear how much he loves his friends, but at the same time very confused by the idea that they might love him. He wants to love others, but he doesn't want to be loved.
When it comes to pure skill, Levi far outranks Eren. Not only does Levi have more experience in the field, but he's also just a better fighter overall. Without his ability to transform into a Titan on command, Eren wouldn't stand a chance against Levi.

Eren was devastated by Sasha's passing. However, because of what he experienced and what he had to do to save the Eldians, hearing Sasha's final words made sense to him and brought back memories of when they were younger, and it was easier to hate the Titans for the devastation they had caused.

Eren is on Paradis island's side. The whole reason for his actions is to protect those dearest to him.
An anti-villain is a character who has heroic personality traits or goals but is ultimately the bad guy in this story. For example, an anti-villain may have noble goals, but their means to attain that goal are evil.
After he found out that humans existed outside the walls and the true enemies were the Marleyans he had to eradicate them since it was the only way in his vision for his friends to lead a peaceful life.
