Why is Sasuke stabbing Naruto sometimes overlooked as opposed to when he did it to Karin?
If anything when it happened to Naruto it was even more brutal.
Nate River once told me that it's different with Naruto since he was fighting Sasuke, but that just feels like an excuse to justify it. I would see it differently if Naruto was also trying to kill Sasuke, but that was never the case.
Sasuke chose to kill Naruto when he was already at his mercy instead of just incapacitating him.
EDIT:
Oh cool you're already here Nate. I look forward to your responses. It's half the reason I made this thread.
