Stage is set for Sasuke
Allrighty then. Let`s have a looksy at some villians in the Naruto series!
-has no heart, so he`ll take yours (and many other people`s since the 1st Hokage`s time)
-stabs himself to extant killing other people in the process
-Killed 2 Kages
-experimented on countless people
-conducted numerous amounts of illegal activities even stirring tension between the leaf and sand almost starting a shinobi world war
-uses a highly immoral immortal tech (hehe, immoral immortal...) which sacrifices people regularly
-did not like to kill people, he would only immobilize them or knock them out (before the summit anyways...)
-killed Orochimaru (from what everyone else knows, as if you remember what Suigetsu told the prisoners)
-killed Itachi (who everyone believed to be a bad person)
-failed to kill the Raikage`s brother
-killed Danzou, who was a corrupt village elder and didn`t have a decisive Jounin vote nor a very ethical right arm....
-helped Itachi stop the Edo Tensei Jitsu, effectively saving hundreds or thousands of allied shinobi lives
-now has a new view on life
It seems as if everything Sasuke did was accidentally a good thing. Granted he did attack the 5 kage summit and took the Raikage`s arm, he killed Danzou who`s trust was already in question. Almost like it`s all set up for him to be able to return as a good guy no?
