Why is everyone saying Tobirama isolated them, sure their base was on the outside of the village but they were all still allowed to come to the main city and participate in everything. And they were given a respectable role not garbage men.
Honestly the 3rd hokage is to blame, he knew the uchiha were planning a huge attack and instead trying to negotiate with them, possibly give someone a seat on the council or let them live closer to the village he sent a spy in and sat back while they became madder and madder. Even Naruto would have Talk no Jutsu some sense into the uchiha elders and tried to get them to appreciate their role in the village.
But its also the uchiha clans fault, they probably wouldnt be satisfied until they were controlling the village and would continue to complain until eventually planning a huge attack. Its not itachis fault because if he didnt do it, someone else would.
