I still don't believe Naruto's past was that much more traumatic than any given real IRL person who is alone from time to time. That's not to say it's a good thing, but it's not special enough to be called a mega-rough past IMO.
what?! he had no parents and no friends for atleast 10 years, how can you say that isn't horrible. Plus on top of that every grown-up gave him scornful looks all the time.

Sasuke and gaara atleast had family.

IMO
1)Naruto
2)Sasuke
3)Gaara
