Re: if sasuke actually killed naruto..
I would be a bit dissapointed, but I wouldn't care too much. It would kind of make sense that naruto would hold back because of his love for sasuke, so it's not impossible.
But the base would be chaos itself.
From what I could tell, there are more sasuke and uchiha fanboysd in here. Not only that, but sasuke fanboys seem to surpass the regular fanboyism stupidity. They are even more stupid and annoying.
Considering this, we would have threds every minute about "lord sasuke solo god" for some weeks.
