He's selfish for abandoning itachi's wishes and betraying everyone. I have to admit though i do like when he battles, sometimes even more than Naruto. SOME of Naruto's battles fail cause hes too soft Sasuke is always out for blood.
After watching the anime and reading much further ahead in the manga, i doubt he will ever go back to Konoha. I use to want him to, but now it' just like wow get over yourself. He not avenging the uchia with his actions hes slandering them.
