What i find more interssting is that Sasuke i being refferd as a "true avenger".
So i he gets his revenge vs Konoha and the manages to live what next?
Will he get upset over the smallest things and just avenge the birds for singing etc

What i think also otherwise is that wich ever wins Naruto who is "good" or Sasuke "evil" may determine how the ninja world goes on.

Lets face it Naruto Kuuybi mode/sage mode (and he might have the sharingna cuz of itachis doing) is to imba. Sasuke managing to beat him would make him even more Imba.
