It’s true I don’t consider any of them as actual evil ppl, even Akainu, I just see them as people working under a super corrupt system. People like Kizaru (smug asshole) and Sengoku/Aokiji (have a conscience) just follow orders, Akainu is just super radical, idk what happened in his past to make him this way but it doesn’t help that he works for a system(the only law enforcement that exists) that enables his actions, he’s blinded by hatred but I don’t he’s truly evil to the core. Lucci is someone I genuinely consider evil because he relishes in it he loves being a dog to the celestial dragons and he loves inflicting pain onto others.
Long story short I don’t think the admirals are evil, I just think Akainu and Kizaru are assholes that need to be defeated and replaced and obviously we don’t have anything on Greenbull just yet. Hopefully I made some kind of sense lol.
