As to what remains of the kings that was not purified: this means that the damaged parts prevent certain laws contained within the governmental order from operating now, and the same applies to certain parts contained within the independent realms and beings that are ruled by it. These laws are the laws of perfection, under which there will be no more evil at all. The emergence of these laws comes about through the constant process of sifting and purification that is going on with steadily increasing gain each and every day, as will be explained in its appropriate place.
And when they complete their process of purification and come to full existence, they will do what is within their power so that there will be no more evil in the world, leading to a state of repair that cannot possibly be followed by any damage whatsoever.
