It's obvious that Naruto is just using Sasuke's own words against him. It's obvious it was not just his body that reacted. He couldn't even do anything until he learned how to levitate. You can tell how greatly upset Naruto was with Sasuke's statement:
Look how dark Naruto's face gets, when Sasuke says he saved Sakura and Kakashi just because they were next to him. Naruto doesn't have these rose-tinted glasses that some say he does regarding Sasuke. He knows more than anyone how "rotten" Sasuke has become.
Will Kaguya get sealed? Usually the objective you declare isn't the one that will be used in the end, but we'll see. I'd imagine it would be more difficult than that. Also, seal her? Highly doubtful that will happen in the end. Sealing her gives possibility that she mightbe able to come back again. I don't know how Kaguya will be defeated, but sealing isn't the answer.
