Since more than one NB existed at the same time, shouldn't they have figured out that the the NBs didn't need to fight to the death in order for there to be a new Commander? I think they know that, but that's their way, as Lexa and the rest of them kept saying. There can only be one Commander, so they have to prove they are strong enough and that they deserve that honor and sacred position, so they do it by fighting and killing each other. The one that survives is the strongest and the only one who deserves to become Heda.

That way Heda's position isn't also threatened by the others competitors, 'cause they're dead.
