I could venture the same about you. The world over - Kage ruled villages - political corruption and Chunin exam blood shed was started by Tobirama. He abolished democracy by introducing a dictatorial set-up where select few people chose the next Kages; the decision to vote in everyone's hands was a yesterday's dream. Not to mention the formation of a separate intelligence division that made that corruption flourish. His system was completely copied by the main villages; Hashirama outright states so in his story.
The village was also made for the safeguard of children and the allocation of equal rights to the founding fathers. He constructed chunin exams where there is a free clause that children can kill other children to gain ranks quickly. He breached the treaty and went behind the settled precepts of Hidden Leaf formation. Who gave him the right to commit treason by spying on a founding clan and abolishing the set political system as he saw fit without the consent of the other clan?
I suggest you read the manga properly, because this man was literally the maw of political filth. Power my ass; spied on them, took away their political right, never gave them equality ... who gave him the prerogative to take the matters into his own hands and warp the original clauses of the treaty? Yeah, no one. Biggest butt-hurt fop in the entire manga. I'll put Obito below him. The dude didn't even spare children. What a great fella.
Bro all this War and Bloodshed started waay before Tobirama become the hokage, have you ever read any warring state era in regards to how both Madara and Hashirama are forced to kill each other, or the time when Kaguya ate the fruit to stop the war?? You make it as seem this is the first time it all started. You're such an idiot for thinking as such.
Tobirama did the right choice by setting up this whole dictatorial system because you can't expect anyone to be authorize the village when they don't really qualify to be the leader. How can you expect anyone to become Hokage when they can't even maintain and protect the village properly. When tobirama became the Hokage, he was Able to Overcome the initial clan individualism and unite all these clans men/woman as one united front. Tobirama created the stability in the first place while other new Gen Hokage must maintain it.
Tobirama even establish the Uchiha clan as a Prominent Clan within Konoha itself. Despite everything Tobirama has done, the Uchiha are still overly Obsessed with being part of the Village and following Madara prospect by doing the whole coup de tat which is considerably a huge threat to the Leaf village which is why he placed them under surveillance. Kagami Uchiha admired and respected Tobirama as a Hokage because he understood what's he's doing that the Uchiha clan need to be in this possession in order to maintain the balance for the village.
Tobirama worked behind the scenes to achieve political stability and implement the institutions that made the village work, thus ensuring Konoha's prosperity.
Even Itachi despite not agreeing Danzo way, he made his choice regardless to wipe out all Uchiha because they are too Butthurt about domination. Uchiha would never been Wiped out if not for the fact that Danzo stole Shiushi eyes.
Again, you made another misconception with your statement, Tobirama is not the only person to break peace treaty, you asserting too much without any prove as to who started this war. The war repeat itself after the death of Tobirama, yet even worse. In fact it was mostly Danzo and Black Zetsu who lead the cause of this whole war.
In the Chuunin Exam, Konoha Policies are not to kill each other in order to gradutate, Mist Village are different when Zabuza stated.When Orochimaru attacked Sasuke during the forest of death, Anko and her squad went in to rescue of course she couldn't stopped him, but however Third Hokage could not postpone the Exam because that will fall the hand of the enemy.
However if what you said are the case, then even then, the student are willing to take the risk and aware of the rules which is their problems. Shinobi are meant to take this procedure. But this is as
" IF" what you said to be true. Here's another If. Even when the Chuunin exam political are corruptted, then why the Third Hokage and the rest of the Hokage still allow such concept and why the clans allow the consent for their children to become shinobi in the first place??
This further prove that Tobirama is remained the most realistic about his ideal and he thinks what's best for his village.
Again this is IF.
Moving on. The difference when He became the Hokage, he reduced the amount of wars, casualty and bloodshed. Tobirama is the best hokage and you know that, but the Uchiha are just too obsessed with powers, how their lost love ones became the strong hate. Tobirama once again label these facts on the table and you call Tobirama butthurt, MY ASS!
