Why didn't Naruto have to reincarnate his parents after the End of the Fourth Ninja War? Personally, I think that it is mainly caused by Naruto's human design and the unethical rebirth skills of the dirt, which is explained below.
The skill of reincarnation is unethical, Naruto's character in the plot is very perfect, and there is a high probability that there will be no situation of relying on the rebirth of the dirt to resurrect his parents.
Many Naruto fans have discussed whether Naruto, who lacks parental care, will use the dirt to reincarnate his parents. Some Naruto fans believe that the reason naruto can't use the dirt to resurrect his parents is that he won't use the dirt rebirth skill, and I personally think that this hypothesis is less and less likely to appear as Naruto's overall level increases.
Especially after the end of the Fourth Ninja War, the ninja world entered a period of relative peace, Kiba Village was served by Kakashi as Naruto, Naruto's work burden was not much, it was not impossible to spend a few years studying the rebirth of the dirt, the factor that really restricted Naruto from using the dirt to resurrect his parents was that the skill of the rebirth of the dirt was contrary to ethics: after the character in Naruto died, the soul would go to the Pure Land (that is, the destination of the soul), The various resurrection types of ninjutsu skills in the plot actually undermine the conventional ethical settings of Naruto's worldview.
Naruto's character is not actually a role that breaks the constraints of the old pattern, and on the surface it seems that the ninja world ended the turmoil at the end of the Wind Transmission stage, but in fact, the five major powers still have an absolute advantage, and the survival status of the weak and weak countries has not improved much.
Since Naruto's human set is a character that follows tradition, naturally it is not possible to destroy the settings in the old system at will, such as the question of the fate of the souls of the living, old, sick and dead in Naruto, Naruto will not do it even if he has the ability to resurrect his parents, after all, the reincarnation skills of the dirt are limited, and it is not really to resurrect Naruto's parents.
In order to achieve the rebirth of the dirt, it takes a living human carrier to succeed, and how can Naruto's human design sacrifice others to fulfill his wish to resurrect his parents?
Many Naruto fans have ridiculed Naruto's character as too idealistic, after all, Naruto as a ninja in the plot actually did not kill one person, which is too strange.
From the characteristics of the ninja profession, it is difficult to avoid not killing the killer in order to complete the task, but Naruto has done it, and since there is such a tall person, Naruto cannot use the skill principle of resurrecting his parents in the rebirth of his parents, which determines that Naruto cannot sacrifice the lives of others to achieve his plan to resurrect his parents.
The rebirth of the dirt requires the use of the living human carrier (above) as a container to carry a specific soul, and once the rebirth of the dirt is successful, the living carrier basically receives a box lunch.
In Naruto's human setting, even if he had more reluctance and longing for his parents, he would not reasonably use the lives of others to resurrect his parents to achieve a short-lived family reunion.
Therefore, the reason why Naruto did not use the dirt to resurrect his parents in this case was not a matter of technical level, but the limitations of the character design and the ethics of ninjutsu effects.
Finally, I personally think that the reason why Naruto did not use the dirt to resurrect his parents is not complicated, on the one hand, this skill is contrary to ethics.
On the other hand, if Naruto uses this trick to revive his parents and the Naruto set up in the plot, there will be a conflict, plus the skill limit does not guarantee that the resurrection time is too long, so Naruto did not use the dirt to resurrect his parents, please forgive me if the analysis is not in place, you have other ideas Welcome to leave a message to discuss.
