Um if sasuke even attempts to kill them then naruto would tombstone piledriver him to hell and make his ass hold that thought.
1) Sasuke doesn't know Edo Tensei are not affected by I.T.
2) He needs Naruto to defeat Madara. Naruto needs Sasuke as well (needed to add otherwise would be called Naruto fanboy)
3) There aren't Zetsu clones on the battlefield to use Edo Tensei. Plus, you need some freaking DNAs of strong people.
4) If Sasuke alone gives his 100 percent against Madara, he'll 100 percent get defeated by Madara.
5) It's Sasuke's Susano'o which is capable of stopping the Moon's light to pierce through. If Sasuke releases Susano'o then he'll also get caught into I.T.
Are you saying Naruto is only good for clones?That is actually a pretty good solution to the entire problem at hand. Kill Naruto and then use Kakashi as a live Sacrifice for Naruto. That way, Sasuke will not have have to shoulder the burden called Naruto. If I remember correctly, Hashirama gave something to Sasuke to seal Madara off. Whether it's still viable after his two transformations before or after absorbing the tree remains to be seen. But Naruto can prove to be an asset because of his ability to make clones.
Use Sakura's live body to resurrect Itachi. He can bring out sword Totsuka and Mirror Yata to help out. That way, two useless pieces of shit will be out of the picture. Itachi is much smarter than Kakashi and Sakura, and two Uchiha Prodigies can turn the tide of the battle easily. Good thread and + rep.
