I don't understand how one can hate Luffy and pirates so much to support absolute bores like the Admirals (Aokiji and Fujitora the only good ones), but it's gonna be very fun seeing the reactions here when the exact reverse of Sabaody happens in the next few chapters lmao
You're asking why we don't support murderers and rapists and are actually rooting for the organisation that's trying to keep those criminals in check ?
Besides that the Admirals have quite consistently, with the exception of GB, have been more interesting personalities. Not only them, any major character tied to the Government is almost always better than those of the pirates.
The best arcs in this series have always been Government/Navy centric.
Also. Admirals have cooler looking abilities.
