Re: Should Obito be the main antagonist?
In terms of the narrative as it stands, there's still no character who serves as the overarching villain in the same capacity. Madara frankly has no personal tie to the main characters except as being the jackhole who set Obito on the path of evulz and gave Nagato his eyes. Sasuke's role as a villain doesn't fit with the scale of the story anymore. Orochimaru cannot pose a realistic threat to anyone.
Personally I just wish Obito's character weren't the same bullshit as Pain and that his reason for falling from grace wasn't so fucking shallow. Obito being Tobi may be absolutely fucking idiotic, but Tobi as entity in the narrative has the most importance as a villain.
