1st point: Kyubi is obviously in some way a part of Naruto's genes because in what other way could Naruto heal so quickly.

2nd point: it was said farther up that if Naruto dies, Kyubi will be released..That's wrong. It's already been stated in the sereis I beleive that Naruto's death equals death for kyubi as well...in wich case i don't know why the nine-tails wasn't sealed in a prisoner or something and just killed the dude..hmm..I might be wrong...

3rd point: No way in HELL should that guy have a kid with Sakura.....Thank you.
