cool. i believe shanks was behind buggy's mystery illness and ace becoming a persona non grata for the WG.
Do you know that Oda literally cosplays as Shanks at certain events? Oda worships the guy, and Oda's entire Manga is about friendship and freedom.
If you want to act like Shanks is an evil character, you can, but you're just ignoring Oda's entire presentation of the Manga while doing so.
Critizing Shanks is fine, but acting like Oda is going to turn Shanks into some evil dude who poisons his friends is ridiculous. Shanks barely shows up in this series, and, except for the first appearance where his editor forced Shank's arm off, all of Shank's appearances have had him overwhelming his foes entirely, or negating them.
The dude who shut down Marineford's war by stopping Akainu's fist didn't need to take out teenage Buggy to be successful, come on.
