I get what you're saying.In all stories the main hero has to have struggles and hardships. It makes them more relatable.
If Sasuke grew up with perfect parents and his clan was never murdered by his Brother and Obito, would it still be the Sasuke his fans have come to love?
If Naruto grew up with his parents and never became the Kyuubi Jin and thus be treated as an outcast and was simply the child of prophecy destined to save the world, would we or his fans have cared to read it?
You guys don't get the point. Minato was already going to die after being stabbed by the Kyuubi's nail.
Same way Hiruzen performed RDS with 2 shadow clones while under genjutsu and sealed away both Hokages, and then even after being stabbed by orochimaru, still managed to get his arms.How does she hold Kurama down with the chains and perform RDS at the same time?
they were both stabbed by kurama i dont think they could survive that.
Because he had Sakura, a medical ninja.<< that is the only factor that was missing in Minato/Kushina. Since the Sage implied he isn't reponsible for Naruto getting better.
And then we also don't know if Minato by himself can seal Full Kurama, that he isn't the jinchuriki for.
