King Fritz is the villain responsible for the majority of the terrible things that happened in Attack on Titan. As the king of Eldia, he was very cruel to his slaves and had one of them, Ymir, hunted down.

Eren's Answer
A tense moment in both anime and manga is where Eren has a talk with Armin and Mikasa in Marley after Sasha's killer was revealed.

Due to his development, Eren recognize that everybody is the same including his enemies. Most notably is Reiner Braun, who, despite committing heinous actions that Eren despises him for, was able to relate with him as both him and Reiner are achieving a selfish goal under a guise of noble ones.
Armin is one of the few kind and pacifistic characters in Attack on Titan. As a child, he won't even attempt to lay a hand on the local bullies, even as they mercilessly attack him. As the series progresses, though, Armin doesn't have a choice but to accept some of the Attack on Titan universe's harsh realities.

Even with all of his strength, there are still a few characters that Goku cannot defeat, and Eren is nowhere near their level. After years of training, Goku can now use Ultra Instinct, a special transformation that puts him at the same level as a god.
Regardless of the form Attack on Titan's protagonist takes, Thor Odinson can easily defeat him. Despite being in Attack or Warhammer form, Thor can easily call lightning down to the nape of the Titans, eliminating the form and Eren in the process.
Zeke is more powerful than Eren while Eren is stronger than Zeke. Zeke has a royal blood while Eren doesn't. Zeke can turn humans into pure titans and he can control them since he has a royal blood while Eren currently holds three titan powers.
