Board Thread:Naruto Discussions/@comment-26773508-20150905054531

Ok I haven't checked if this topic has been dealt with before, since there are way too many threads in this category and it's tiresome to check all those. But I've always been wondering: why did Kushina need to die if Naruto could survive Bijuu extraction with the help of Yin Kurama. To clarify, we all know that jinchurikis die if their Bijuus are extracted from them. Kushina was able to survive the extraction for some time because of the strong life force she possessed due to being an Uzumaki. But in the War, we've seen that Naruto was able to survive Bijuu extraction after Obito sealed Minato's Yin Kurama into him.

So my question is: '''Why didn't Minato reseal Kurama into Kushina so that she would survive? If she resealing Kurama wouldn't have saved her, then how did Naruto escape death through the resealing of Kurama?''' Aren't these two events contradictory? So is it a plot hole? Or is there actually a valid reason given by Kishi that is consistent with the manga lore that he himself created? I haven't come across any valid reason so far, but that may be because I'm a bad reader. So please, can anyone clarify?

P.S. If this topic has already been explored, then can someone please send me the link of that thread? Because right now, I don't have the time to check all the 300+ threads in this category.
