Coming into this one a bit late. I've made the point before that I think this is a conflict with a difference between eastern and western notions of story telling.
We westerners like the big ending, everything tied up in a bow, we want a definitive conclusion to the tale.
Many Japanese stories (which you can see in a lot of anime before it was more westernized but still see it some today), have this element of "we are talking about a moment in time, and the journey always continues, with more love, more battles, more death, more life". So there is this element of "and the hero continues the journey" without any real conclusion.
In many ways as the execution is about to take place, and we hear laments about all of the battles and schemes and plots that they will never get to see or take part in, that is also meant as a relation to the audience, and ultimately to life. The audience will also never see those plots and battles and schemes....because in life there will always be more beyond what we get to see, new stories we will never read because we get X amount of time, and then its on to the next person.
