@MIGshinobi: We can't absolve Tobirama of his mistakes completely. What raises my eyebrows is the fact that a lot of the people in the fandom put the blame fair and square on Tobirama, and Tobirama only. They ignore how much Madara and Obito fucked up the world.

As I and others have argued, Tobirama is the ultra-rationalist type who only relies on strict observation and logical inductions/deductions made through those observations. Remember, Tobirama spent his whole life studying the Uchiha and the Sharingan. Heck, he even preserved Madara's body for a while to study his Sharingan. Considering the portrayal of his character in the manga, it is highly unlikely that he was lying when he said that he saw many Uchihas in his lifetime turn batshit crazy. He also claimed that the Uchiha were much more vulnerable to such violent tendencies more than any other shinobi clan he knew. The manga has shown no hints to doubt Tobirama's words on this.

Tobirama also figured out the mechanics of the Sharingan and its higher forms. And he realised that the Sharingan's power is, in many cases, directly proportional to how much pain and loss its wielder feels. Like @Hereticalthoughts said, the Uchiha not only were predisposed to a form of psychopathy, but they were also potential psychopaths with magical eyes of mass destruction.

A talented shinobi from other clans could reach god-like levels from enormous willpower, training and effort, but all a talented Uchiha would need is a single personal tragedy to transform him from a regular shinobi elite to a virtual god. Just like how in the Injustice comics Batman realised that Superman's unimaginable personal loss combined with his godlike powers would mean the subjugation of the world into virtual slavery, Tobirama realised that the Uchiha with their unstable emotions and their magic eyes would eventually lead to the destruction of the Leaf. The difference is that Tobirama tried to channel the Uchiha's powers by making them the guardians of the Leaf, while Batman directly went on the offensive without giving Supes much of a chance. Tobirama's plans failed, but at least he tried.
