@Cyan:
To be fair pretty much every problem in this series can be traced to Tobirama being an asshole.
Nah, not really. It's more of a Uchihas being overreactive assholes. And Hashirama not killing Madara, when everyone would be totaly okay with that.

@Cyan:
I hold Tobirama in higher contempt than Madara because he's the asshole that made the stupid zombie technique for some godforsaken reason.
It's pragmatic. I mean, think about it: After you take enemy soldiers prisoners, and torture them for information, instead of just throwing them away into some prison, you used them to revive some of your fallen comrades. They, in turn, will kill at least several of your enemies before they can be sealed away. And thus we save several lifes of our own troops that would have surely died if we attacked the enemy head on. We also solved problem of housing prisoners of war.
And morality? We are using child soldiers, who cares about morality anymore.
Wanna blame someone for it, blame Sarutobi, guy that maked security of scrolls with forbidden techniques so lax that 12 year old child could get in and steal one.
