User blog comment:Observer Supreme/How would Kizaru and Aokiji operate if either of them were Fleet Admiral?/@comment-78.0.126.77-20170719000221/@comment-25400375-20170719011156

Sounds plausible. Considering the Warlords are important assets for whatever reason, though, I'd be in favor of encouraging respect and trust between them and the Marines and when the time comes to disband them, allow them to keep their pardons so long as they don't commit new crimes. Of course, that's probably what Luffy would say if he was a Marine, but that's beside the point.
