Even if Madara became Hokage, it would not have stopped him from leaving the village and carrying out the eye of the moon plan, which means it would have not prevented anything. Madara, like many other Uchiha, suffered from the curse of hatred. When Izuna died, he gave into his Curse of hatred. After he was defeated by Hashirama, he briefly overcame it, but only to fall far deeper into it after he realized that his and Hashirama's dreams for the future was not the same. Madara, like Sasuke, suffered from a dual superior/inferior complex. He felt superior in his abilities and heritage, yet he felt inferior to Hashirama and all that he had. He was bitter, sore loser who directed all of his hatred at Hashirama at the VoTE. Being Hokage wouldn't have helped him, because he still felt inferior to Hashirama. Madara gave up everything for his "dream ", his clansman, friends and the village, that makes him a bad leader.

Hashirama, was a great Hokage. He managed to maintain the power balance between the villages and promote peace. One of the reasons why he was a great Hokage was due to Tobirama being at his side. Tobirama didn't look at the world the way he wanted it to be, he looked at the world and saw how it was. He foresaw the possibility of the Uchiha turning against the village and actively did something about it. He gave them the job of policing the village to instill in them the notion of protecting their village, to keep their curse of hatred it check.

Tobirama cannot be faulted for trying to help the Uchiha in overcoming their curse of hatred. The fault lies with Madara, Obito and Danzo (and of course Black Zetsu), they are directly responsible for the Uchiha massacre.
