So what did he have to do? Split it in ten different separate beings so it doesn't come back. As far as we know, you can't kill the Ten Tails.

i am sorry to told you super kurama that no one can defeat the juubi because he can't die he isn't a living he's only chakra taking form of a monster and chakra can't be killed but sealed into a person :)
