Why did Watergate only seal half of Kyubi no Youko and chakra on Naruto?

I was a little surprised to see this problem just now. When did Naruto only have half of Kyubi no Youko and chakra? Later, when I went back, I found that the reason was that I fast-forwarded the last World War IV and ignored the important plot. Later, I went back and watched it again, only to understand why Watergate only sealed half of Kyubi no Youko and chakra in Naruto's body.

First, let's talk about the deaths of four generations of Huo Ying couples. At that time, Watergate had a fierce struggle with masked men, followed by a desperate struggle with Kyubi no Youko. When he died, his brain was wide open and he decided to seal Kyubi no Youko in Naruto's body. Even if Naruto's body is in danger and talented, he is just a baby anyway. I guess he is afraid that his body will burst with too much energy. So from this perspective, Watergate had to seal half of Kyubi no Youko chakra into Naruto's body, but it was also half of Watergate himself, Kyubi no Youko chakra.

Let's talk about the benefits of Kyubi no Youko and chakra. Without it, the "technique of multiple shadows in two places" tailored for Naruto will never be cultivated. Therefore, this is a life-saving skill for Naruto, who was weak in the early stage. It is the existence of the technology of multiple shadows in two places, so Naruto can develop stronger endurance, as follows ↓

Glasses think twice, only to find that Naruto seems to have no other ninja skills except spiral pills and various improvements. It can be seen from Naruto's practice of spiral pills that his talent is not a wizard, and he needs the help of a shadow avatar. This also makes Naruto need the technology of multiple shadow avatars, and also needs Kyubi no Youko and chakra to maintain it. So Watergate is really good at predicting the future.

Although Naruto was once the pillar of Kyubi no Youko, which was once rejected by the villagers of Konoha, it is not easy for Naruto to finally have the feelings of loving the world. In my words, it is a negative example. Fortunately, Naruto was forcibly washed away, so to some extent, it is also a test of his son's mind to seal Kyubi no Youko chakra into Naruto. Of course, we don't know if he thought so at first, but there is another point that also illustrates this advantage.

Naruto was accidentally pulled out of Kyubi no Youko in the Fourth Endurance World War. At this time, even the woody cherry was at a loss. What other methods can solve the problem? At this time, Watergate appeared again, sending Kyubi no Youko and chakra into Naruto's body and implanting another one in his body, so that he could be resurrected in the same place with blood. This is the biggest foreshadowing of the film, which begins with glasses and has nearly 700 episodes in the middle. Generally speaking, the advantages of sealing half of Kyubi no Youko and chakra in Watergate outweigh the disadvantages of Naruto, provided that this person is the leading actor. If it was Sasuke, it would have been dark!
