Naruto Chapter 603

Because Edo Tensei requires live sacrifice? I dont know if regular village people would be down with that.

It requires a dead body, but there's no reason you couldn't use a recently dead person who died on the battlefield, or even better, just use the technique to resurrect the same person you just sacrificed. It'd be like going under for surgery. Me and DS hashed it out and determined that you could basically solve all societal problems with judicious use of Edo Tensei.

EDIT:

I actually just read that chapter where it has to kill a still-living person, but there's no reason you couldn't daisy-chain it to resurrect the soul of the person you just used previously, and have some death-row inmate provide the first sacrifice.
