I think the only thing that could make this worse for Admiral fans...
Is if the Admiral died protecting a Celestial Dragon
Admirals need to rebel against the WG in order to pursue their true Justice. This series is all about Will and Freedom, and Oda's made it clear that all the Admirals (besides Aramaki) DESPISE the limitations the WG puts on their justice. Hell, Kuzan just left because of it.
I think Fujitora will be the first Marine to truly rebel, and we'll see him use CoC/his true power as a result.
It's impossible to say Marijoa didn't limit this Admiral: nothing limits the justice of the Marines more than the WG's Celestial Dragons. If these sex traffickers had no power, THE ADMIRAL WOULDN'T HAVE BEEN IN MARIJOA TO FUCKING BEGIN WITH
