I think a perma death should only be allowed to characters who achieve something worth protecting. For instance, learning to wield a third nature. And something like that is only allowed once they master the other two. But once they learn their third nature, a price should be put out on his head or a mission granted from the Kage to Anbu skill lvl shinobi. This way, once that person is able to weave two chakra natures (making them overpowered), they will have to be cautious when using it. So that even those they once called friend won't be temped to kill him to collect a huge reward. I think this would also allow for a better system for handing out keke genkai, so that it isn't random. Instead given to those who have earned it, and kept by those who master it. However, once permanently killed the keke genkai is handed to the Kage for reward. If kept that person, is now branded a rogue and the cycle continues. I think this can be done with more than chakra nature based justu, maybe even make room for ocular abilities.
