Also, it makes no sense that Naruto, who was raised as an orphan, would be so unwavering committed to the village, the rookies, his teammates, etc. While Sasuke, who was raised as part of a larger and powerful clan, would be the one to shun everything and go into a solitary life, giving up his goal of resurrecting any part of his clan. ( I don't count his relationship with Sakura/Sarada cause it was clearly something he invested nothing in.)
It makes no sense that the orphan wouldn't have to come to grips with those feelings of abandonment, and the family kid wouldn't have to deal with the fact that he alone is letting the rest of his clan (letting the Uchiha die out) down by going it alone.
No it does. Naruto is desperate to have the bonds he was denied when he was young. While Sasuke who lost it dwells with that lost, focuses on revenge, and doesn't want to try again with other people. The level they go to are absurd because Kishimoto pushed it to those extremes to justify their final fight.
