Naruto 's retcons break the characterisation.
What I pretty much despise in the end is that they made Naruto into this quintessential messiah that all is forgiven after the war. You'd almost be mistaken that the end chapters were ghostwritten by a cult (Fun fact: Japan has a ton of cults, and the government has been cracking down on them for a while).
Try to imagine Naruto being in this manga:

The full synopsis is that a kid was falsely accused of killing his surrogate father. It's set in a dystopia where a meteor struck Japan, and the perimeter of ground zero has been reduced to a slum where the unwanted and undesirables have been cordoned off from normal society. The protagonist, Riku, is your typical Shonen protagonist at first glance, but you'd almost be mistaken again that he's a carbon copy of Naruto. Here is where the difference seems to lie.
I find it telling that in the chapter I posted, the first antagonist that had been bullying and harassing Riku tells his backstory to him.
This is how he reacts afterwards.
The thing that bothers me the most is this. I will bet every ounce of blood in my body that Naruto, in typical Kishimoto dipshit fashion, will tell the guy that he should forgive the man that almost sold him for his organs and remember the good times they had. That would be a case study of someone so desperate for companionship and affection that even some malignant pig that sells children to be slaves or organ cattle is someone that he could forgive because the guy "actually had someone".
That is not a healthy or sane mindset at all.
EDIT: It's also telling that Riku actually lives in squalor. His entire home is pretty much a landfill of garbage, and that he takes refuge in a car trunk. His "Iruka" is murdered and he finds himself in a situation that would break any one. Reminder that this is the characterization that Naruto has in the manga, which you so succinctly pointed out.
He had no one, but he did, but he did not. Naruto is cursed with a demon and that means he is shunned. But no, he is not.
