Sasuke has explored many paths, and he's choosing the one he thinks is best. Unlike Naruto who has grown up with the same motto since chapter 1. Sasuke is capable of accepting changes in his life and and act accordingly.One can submit to instant gratification and then live like a loser for all his life, or you can keep you guard of determination up and achieve new heights.
Sasuke chose the latter, too bad he is fictional to be a role model for the "fix craving" generation we see nowadays.
Can't believe Naruto is so 1-dimensional with little character growth
