Sasuke would have been wrecked if itachi was not there. IMO the Izanami was one of only a few jutsu that could stop Kabuto.

Also, there would not have been much of a 4th war...he made the weak white Zetzu...more useful. And we all know what a nearly perfected Edo Tensei did to the whole ninja world.

I would say he is one of the best villains.
