i see your point, but i still believe that the 8th gate would kill. if you use the 8th gate i think that first off it would consume all of the persons chakra (which would cause death), second thing is it just seems like their blood vessels would explode and probably the heart too (don't forget that the gates make the heart work harder) and i believe that the 8th gate would make the heart destroy itself.
To quote myself:
"However... while a Hyuga couldn't fix the problem, I do believe that a skilled medic [team], someone with a special ability (Hidan, Tsudae, Saukra, Kakazu, Hashirama, Orochimaru, etc) that doesn't let them die, or one who simply used gates 1-7 excessively (as shown when Guy did this and because of such could recover much easier and quicker) should be able to use that 8th gate without death. People have certainly survived ridiculous scenarios in Naruto due to any one of those 3 reasons (e.g. Tsuande healing Choji and Neji after the Sauske Retrieval Arc, Hidan getting his head chopped off, and Kakashi perfecting his Lightning Blade usage by using it often so that his body is now adapted to letting him use it many times more than when he first did, which was only 2 compared to now is, like, twenty it seems.) so I see no reason why the same can't apply here. It should be possible to survive the 8th gate."
But to be honest with you, because of the power it would unleash, I'm sure Kishi will make it one hit KO; I'm just saying I believeit should be possible to survive ^_^
