I am an artist, and my medium is death. I'm about to create my masterpiece :s
Fan of the Rasengan Doujutsu theory, even though it's dead. Although, he does have the special Uzumaki clan blood.
thing is tho, you dont know that, she could have lived a long and productive life as naruto's mother, but the fact remains, kushina didnt die from the extraction itself, kushina was killed when the kyubi impaled her, hence your generalization is anything but justifiable and is flat out wrong but you are right in the sense that all that have gotten their bijuu extracted have died, but not necesarily from the extraction itself with the possible exception of gaara who got revived.
The hosts of the seven Bijuu's that Akatsuki have died from the extraction, but none of them where Uzumaki's, which have the strongest life force in the Narutoverse, as far as we know. There is the possibility that Kushina could have survived and the same goes for Naruto, which seems to have the highest possibility to survive.
ill say what i said earlier, none of us can know if kushina would have survived or would have been killed by the extraction, all we do know that the kyubi impaled her with a claw and ultimately killed her. this is cold hard facts and saying kushina would have died anyway is nothing more than an assumption.
Question: Since Kushina expected to die, and was planning on sealing the 9Tails back inside her, and drag it down into death with her (for a while, until it reappeared), Then was she planning on suicide, or was she dying anyway?
I am not perfect and I defy you to prove otherwise
Growing Old Gracefully is an Oxymoron ... Mostly Moron !
at the time she was severely chakra depleted after using her chakra chians several times and was most likely dying anyway which could have been her plan from the start when the kyubi was released.
