"WOAH WHAT A BASED ANTI BULLYING ORGANIZATION ECKS DEE"
Yeah sure, in the end these cringe flag waving bastards are just manipulating broken people to kill as many people as possible, actual bullies of the bomber or not. Serizawa's bombing still took out some people who never gave a shit about her and she never gave a shit about, while Nakagoshi's bombing was even worse. And of course the excuse by Kaede is "you didn't give a shit about us, so you're even worse than those bullies" lmao. By that logic why not just bomb the entire school and kill absolutely everyone? Or if that's not enough, why not go after every single PTA member as well? Or even the Prime fucking Minister of Japan because he surely never cared that you were bullied!
And the cringiest bit in this manga was that the one who actually detonated Serizawa's final bomb was a teacher - the very same one who we then see is recruiting Akane as the next bomber in the ending. So it was never about caring about weak and downtrodden kids, sounds to me that the guy wanted to be Japanese Johann Liebert but is unwilling to even do the dirty work himself lol.
Only dumb fucks think anything said by these wannabe heroes ever held any actual weight, and the author himself finally gave up trying to justify their bullshit and simply gave the terrorists some lines that made them sound like power tripping assholes to make it a shock ending. One of them literally said that he's bored and thus another bombing needs to happen. Yes, these fuckers do it BECAUSE IT'S FUN. You know, just like the bullies they claim to be fighting against, only much worse because they manipulate actual bullied people to kill tons of people, including the bullied people themselves.
