Minato Could've Saved Kushina

[Honord Sage]

The 9 tails was extracted from Kushina similar to Naruto. Naruto fainted on the spot with just Yang Kurama extracted, while Kushina was still awake after extraction of a full Kurama. Show how much lifeforce she has.

Minato could've sealed the nine tails back to her like how Naruto received the other half of Kurama.

So due to Plot, Naruto parents died for no other particular reason but for the manga to exist.

Just some thoughts

So whose up to see Madara whip some ass?

Wrong,Kushina seal was force open by Obito. Naruto seal was open to let Kurama out to attack Madara. Madara took Kurama outside of Naruto thus Naruto seal was never broken like Kushina was sines Naruto had His key to His seal and Kushina did not.
