The narrative of One Piece doesn't emphasize the adversities that occurred and led to someone's defeat. The story only cares that X defeated Y without giving importance to how it was done. For instance, Kaido could have lost both arms and legs from facing 1000 people previously and ultimately be defeated by Luffy in that sorry state. People wouldn't care about his condition, only that he was defeated, as they know that among pirates, there's no concept of honor, whether Kaido was weakened or not doesn't matter; what matters is that he ultimately lost. That's how One Piece operates. However, this doesn't mean that readers, knowing the full truth behind the events, can't form a different opinion.
