I wanna see everyones opinion on this. I think Sasuke is pulling an Itachi. What I mean by that is that he may be just using Madara to gain more power just like he did with Orochimaru,and he is just faking being all evil,like Itachi did(maybe I am mistaken). If that is not the case I think Itachi will meet up with Sasuke and something will happen that brings Sasuke back.
As much as Itachi loved Sasuke, he screwed him up
He told him that hate was his most
important weapon, yet he didn't clarify why
he should hate.
Itachi's hate was
focused on rendering justice, Sasuke's hate
was focused on gaining power so he could kill
Itachi. Once Itachi was gone he no longer had a
goal that involved justice, all that was left for
him was hate.
In other words, Sasuke is
exactly as he appears to be. The only way he will
flip sides again is if someone can give him
something to live for besides hate.
Sasuke hate is fueled by Madara thus
making more difficult to extinguish. And as for
restoring his clan, IMO what he meant back then
was his clan's pride. Which means he is still
pursuing that "dream/plan", though in a
Sasuke loved Itachi, but I don't think that
he's Pulling an Itachi when he fights with
naruto VS Madara why isn't Itachi there? I
think Madara killed Itachi and thats what drove
Sasuke mad to fight with Naruto against Madara
