Just coming up with theories for this but I'd like to know others thoughts on the matter. And there are revealing facts that some of you may not know yet that I'm about to speak of. So if you are not completely caught up I recommend you back out of this card. Ok so here we go!
We all should know by now that Sasuke left the village in order to gain strength from Orochimaru. My question is... do you think that Sasuke and Naruto would have gotten stronger than they are now had Sasuke stayed in the village and continued to train with Naruto? Or do you think that because of the drive they gained after the Final Valley they were able to become stronger because of it?
