View original postAccording to RJ (which he has stated in an interview)
1) That balefire doesn't destroy the soul forever
2) Just remove it temporary from time
3) Since it is removed temporarily from time it removes the dark one's hold on it
4) Thus the dark one can not resurrect a chosen unless the chosen is reborn and rededicates himself to the dark one, in another life, in another time, in another turning of the wheel.
5) Thus balefire frees the chosen from the dark one.
