Many people think that the tailed beasts are as strong as their tails, but lets be serious. Why should SO6P give the tailed beasts different power levels?
He had the 10 tailed beast and feared that it could escape again.
He was a jinchuriki himself and knew that a tailed beast, even divided could harm many people if other jinchurikis would missuse them.
So the best method would be to let all tailed beasts have equal power. If one is missused, another one can stop him.
And thats the reason why Naruto and Bee are pretty much f*cked, if Naruto doesnt manage to free the beasts and make them friends.
I know that Kisame said the 8 tails is the second strongest, but maybe just cos bee could fully controll him and the 9 tails could easily break out.
they are like the atomic bombs of the ninja-world.
So what do u think?
