Seems like to me Tobirama is not the type of dude to do that.
He does need a living sacrifice which honestly goes against Tobirama's character. Why did he even invent such a jutsu knowing it would cause so much misery. I mean using it against your foe is one thing but you are breaking morals-principles that a respected Kage would not.
Also I could never see Tobirama raising his dead brother to have him powerhouse on some fools. He has way too much respect for Hashirama though I understand your point.
