Oh you...don't you recall?So your comparing the love that your family members give you to random people you don't know? Naruto had a father figure in his life which was Iruka.
Iruka at first despised Naruto because the Nine Tailed Fox inside of him killed his family. He thought he was just a pest.
I'm not saying Sasuke's childhood life was all rainbows and sunshine. I'm just saying Naruto's childhood was worst. Sasuke had people to say "there there." *hugs*, while Naruto had no one's shoulder to cry on for a really long time.
Which makes you think.....Naruto could have ended up turning evil while Sasuke had to save him from his darkness. Naruto said it himself.
