I don't want to spoil anything for people who don't read the Naruto manga but for the people who do read, have you read the lastest chapters? In my own opinion Sasuke is in complete darkness and the rate he is going in will be his downfall or his demise, or whatever o.o;
I can understand how much pain he is in due to with what all that has happened to him but there comes a time where you have to draw the line. As Madara stated Sasuke is the true avenger.
But what are your thoughts on Sasuke.
