Naruto also got stabbed by Sasuke in Part 1 XDDidn't Sasuke get stabbed by Danzo and still stood like G after it while Naruto fell on his knees when the same happened to him? Both were badly injured and needed to be healed but Sasuke looked ore casual and even smiled while Naruto was in much pain.
Probably not as painful as the butthurt I am senseing from your post.
