Floch is an amazing character, regardless of how people judge him morally
With the exception of tiktok, I see Floch hate everywhere, so I wanted to gather my reasons why he is an amazing character.
As the sole survivor of the charge against the Beast Titan, he went through unimaginable trauma. At just 15 years old, he called himself weak, yet he still chose to ride into certain death.
Instead of letting that fear control him, he allowed it to forge an unyielding resolve to secure a future for Eldia. He didn't just survive but carried a dying Commander Erwin across a bloody battlefield and then stood his ground against Eren and Mikasa on that rooftop.
Floch was never weak or spineless. He was a terrified, honest boy who managed to conquer his terror.
He confronted Eren, Mikasa, and Armin with brutal honesty, refusing to back down on the rooftop or at the military ceremony, completely ignoring the social or emotional consequences.
On top of that he entirely abandoned any resentment toward Eren for choosing Armin over Erwin. Instead, he recognized that Eren was the only one willing to do what actually needed to be done. Floch saw a mirror of his own conviction in Eren.
People can judge his morality all they want, but Floch understood Erwin’s ultimate lesson: to change anything, you have to throw away your humanity.
Almost single-handedly, Floch organized a coup, orchestrated an assassination, and built a paramilitary movement. He did this while fighting against the entire main cast, even though he was ultimately fighting for their future, too.
It feels very much like Isayama tried to take Floch down a notch with moments like Kiyomi Azumabito overpowering him. (Which felt completely unrealistic, like it was intended to make him look ridiculous and stop the audience from liking him too much.)
But in the end, when the main cast killed him at just 19 years old, Floch didn't beg for his life. Instead, with his final breath, he begged them not to stop their devil from saving Eldia. He proved his absolute bravery by sacrificing everything for his homeland.
Even Hange ultimately looked at his body and admitted that he was completely right, but they stood against him for moral reasons.
