That makes absolutley zero sense, Naruto will save Sasuke that is what the manga is all about. You haven't paid attention it seemes, it's probably because you're fanboying to much :/
Let's Review,
1. Hashirama didn't want to kill Madara [Naruto feel the same way]
2. Hashirama wanted to save Madara from darkness [Naruto feel the same way]
3. Hashriama wanted Madara as an ally, as a brother for his dream [Naruto feel the same way]
4. Hashriama finally changed when he realized that Madara's going to harm his dream no matter what [Naruto will change the same way]
5. Hashirama killed Madara with a Bunshin Feint [Naruto will kill Sasuke the same way]
