WHAT IF Hashirama wasn't the first Hokage and Madara was!
What do you think will change?Will Hashirama be the 2nd Hokage or something like that and Madara will never fight Hashi at the VOTE .
There would have been piece and the war would be over.
You see it's the same as when the younger brother was chosen over the elder, the same happened with the descendants, but tbh there still could have been peace, Madara chose war, the Uchiha were still making decisions in the village, but after madara's attack naah.
The Uchiha have too much arrogance and can't accepted power that exceeds there own, that's the reason for the war between Uchiha and Senju.
Also the fact that Sasuke had the confidence to storm a kage summit tell you a lot about the Uchiha logic and the idea that they have about their power compared to that of everyone elses.
