The reason I brought something from last year up is because your argument now is weaker than mine was then. If you don't like my old argument, you shouldn't like yours now. It is too easy to hold other people to a higher standard than you hold yourself. Hypocrisy.

Let's compare. I said there were some things in common between Madara and Danzou, including:

1) Their training methods. Madara made the Uchiha kill each other off as a training method. Madara made the Land of Mist kill each other off as a training method. Danzou made Roots kill each other off as a training method.
2) Their politics, including the manipulation of Pein, which they both took part in. Also includes the building of personal armies with the backing of the Hidden Villages (Roots, as compared to the Land of Mist coup)
3) Their ages, similar looks, and conveniently placed mask/eye hole.

All of this can plausibly be understood as foreshadowing. Yeah, I was wrong. It was still a stronger argument than yours.

Your argument: Madara is somebody else because characters acting AS THEY SHOULD "means" that he is somebody else. Really? That logic is weak.
