itachi is a murdeorus selfish traitor. he helped murder the jins in cold blood and in such a way that basically ensured the akatsuki got their hands on living nukes. he could do what you said but thatd require a brain and care and concern for others besides his brother.
but like sanbi after a few years they would have come back
sealing doesnt mean dying. you cant just respawn out of a sealing pocket dimension
. I'm just trying to say that if he wanted to stop Akatsuki from getting all 9 beasts he could've done it quite easily,
but like ive said, itachi is too selfish and insane to actually try and stop bad people
he bijuu would be revived,
from what? he wouldnt be damaging them
It's just like saying Itachi could have done better than Kakashi, Gai, Killer bee and Naruto at the same time...lol sorry he wouldn't have
no one said this would be every biju at once in one location
