Tobirama was a BETTER Hokage....
This is not a versus thread! Please do not bring the battle prowess of the brothers, as that is not what this thread is about.
Now with that out of the way, time for the questions.
Out of the two Senju brothers, who do you think influenced Konoha and the ninja world the most?
And whose influnce was more beneficial for Konoha and the Ninja World?
Hashirama was one of the founders of Konoha, he initially set up the village and was the leader until his death. During his term as Hokage, he did many a thing that would influence the entire ninja world and Konoha.
As everyone knows he fought and defeated Madara Uchiha, who also wished to lead Konoha. That in itself is beneficial for Konoha...Or is it???? Thats a different thread altogether.
In defeating Madara, he gained the 9 tails, which to this day has been under Konohas control. It is definitely a good to have in case of war, defensive or offensive.
With that he also distributed tailed beasts to the different villages around the ninja world. To "even" things up, however these have always caused trouble in every village, with hundreds dying in the attampt to restrain and control them.
Definitely the most influential thing he has done for Konoha is the The Will of Fire. "This is what gives Konohagakure shinobi the strength to continue fighting against all odds, building willpower and strength of character. It is also symbolic of the hopes and dreams of the previous generation being passed to the next"-Narutopedia. All ninja in Konoha live by it and it is what pushes Naruto to protect the world. This was a senju belief and both Hashirama and Tobirama passed this on.
Now finally Hshiramas final influence on the ninja world was his DNA itself, this is definitely a negative influence. Ninja have always coveted it, Madara used it to gain the Rinnegan and live until he meet Obito, when he was reanimated he used it to help him defeat the five kage and now control the Juubi. Obito is half Hashirama DNA, this also allows him to use Mokuton, boasts his use of Kamui and control the Juubi using his Rinnegan and Mokuton. It has also been used to create 100000 zetsu clones, which have killed between 20000-60000 ninja from every village.
Tobirama was also a founding member of Konoha, and also had a major impact on the ninja world.
During his reign after Hashiramas death, Tobirama set about reforming the village, much like Caesar Augustus. He set up many organisations in Konoha which over the years would be adopted by every single major village and many of the smaller ones, these included the ANBU, the Academy, the Chuunin exams and as everybody knows he made the Uchiha, the leaders of the police force. Every single one of these are beneficial for Konoha and also the ninja system in general. Adversely making the Uchiha the police force has had very dire consequences, however at the time it seemed to him the best thing to do, as they were definitely suited for it.
He also had some other influences on Konoha for example he created all the infrastructure in Konoha, he formed an alliance with Kumogakure, during which he was almost killed. And he was a firm believer in the Will of Fire, instilling that into the Hiruzen, who instilled that into many a shinobi including Naruto himself.
His negative effect on the ninja world is a big one, he created the jutsu known as Summoning:Impure World Reincarnation. This technique has caused major heart and headaches for the ninja world as a whole. During the Konoha invasion arc, it was used to kill the third Hokage, Hiruzen Sarutobi by Orochimaru. Later on Kabuto used it to someone 30+ of the strongest ninja in history, this technique caused the defeat of every Kage and countless fodder ninja who lost their lives fighting the Edos.
Now to the answer the questions
I believe Tobirama was more of an influnce on the ninja world and Konoha than Hashirama was, and i also believe it was for the better. The only thing Hashirama did for the benefit of Konoha was creating and defeating Madara, which may not neccesarily have been a good thing, and preach the will of fire. Tobirama revolutionised ALL the villages for the better, and was also a firm believer in the Will of Fire.
The decision comes down to their negative effects Tobirama indirectly caused the Uchiha clan slaughter, he also made Edo Tensei, which is obviously a justu that has caused vast amounts of deaths.
However the use of Hashirmas DNA is far worse....It allowed Madara to use the Mazou, which allowed him to live. If Madara had not survived, neither would have Obito as Madara(using Hashi DNA) used Hashi DNA to restore him. Madara turned Obito into what he is today, that same Obito who released the Nine tails and had both of Narutos parents killed. That Obito who created Akatsuki, which made Nagato destroy Konoha. That Obito who has captured 7 bijuu and has started a war against the ninja world killing 70000+ people.
Result: Tobirama Senju may have been weaker than Hashirama, but he was far the better Hokage.
