What happens when you wipe towns off the map and destroy countries?
People survive?
There's been multiple instances where town was fucked and people survived lol. Xebec's own son did that in Banaro island.
Also, roger is framed as a good guy and he wiped out countries for shit talking his crew.
Condom is the good guy MC and he literally freed heinous criminals to rescue his pirate brother.
Good and evil are a matter of perspective.
Why would we need to? We also don´t know the inner workings and machinations of Doflamingo, Kaidos, Big moms and Crocodiles mind or goals. What we need to see is how they themselves frame their positions. Xebec has never framed his goal as anything other then wanting to be king of the world.
Except we do. We have gotten glimpses into all their psyche and their deeper motivations or lack thereof.
Doffy is insane from his childhood and wants revenge on the CDs. He also doesn't care for normal people cause of his past.
Kaido wants a great death, and he isn't above slavery, torture, murder and all that to achieve it.
Meme is extremely damaged mentally and wants a twisted equality.
Croco wants his own country ala Doffy, and he is willing to do anything for that.
None of those is the same as wanting to be the king of the world by overthrowing an authoritarian and totalitarian govt.
Lol,why doesn´t he mention that then? How are you accusing me of doing conjecture, when you make up your own story about Xebec ¨disliking Imu´s evil deeds¨ as opposed to his actual goal, which is just to be King of the world. But let me guess, he only wants to be King of the world to make the OP world a wholesome chungus paradise.
Yes.
Xebec just wants peace for the entire world.
What a man he was
Why would we frame it that way if the man himself doesn´t do so?
Xebec doesn't have to hold up a sign saying "i am doing this to rid the world of imu the evil" for us to know that.
It's called reading between the lines.
The fact that his first scene in the manga was in imu's room says a whole lot about him. He and imu and intrinsically linked and dichotomic. So if imu is evil, which we know he is, then Xebec is the opposite side, which is good.
