What the hell?
It's not reeeeeally a fucking suicide pact, is it? I was worried before with the spoilers, but it's not that bad, calm the fook down. He sees Sasuke as his burden, and his burden alone (which is somewhat annoying, but screw it). If they both fight each other properly (which is an immutable given, anyway) they'll end up killing each other (possibly). Naruto's not thinking: "Sasuke, babe, I can't live without you, come back to me otherwise we'll end this all now!". Calm dooooown.
We all knew there'd be no Naruto without Sasuke, it's simply the way of this manga. Chill your heels. Naruto has a cunning plan.
And yeah, it was always going to sound distinctly homosexual. It's Naruto, bless him.
