And this may have been answered before, but what exactly is the NK / WW end game? What do they want? Revenge on mankind? To watch the whole world burn / freeze? To kill them all?
Back in the old pre-show days on westeros.org, there was an intriguing fan theory about the WW - that they were back and attacking men because in centuries past the Wall was supposed to be the dividing line between the Realms of Men and the WW (Others) territory, and the humans had been encroaching for years. In essence, the WW were attacking not as aggressor but as defenders pushed beyond all reasonable limits. Like most fan theories it was ten times more complicated than necessary, but when I went looking for it recently to brush up on the specifics I found this much more succinct version on Reddit that brings up the highlights, specifically remarking that a massive, 100% good vs 100% evil struggle is just not in the DNA of this story. Sure, the myths that have been told about the past are always heroic, but the actual events are much more complicated.
Here is the link - no show spoilers at all, it's 3 years old and is 100% book based (so there are references to things like Robb being a warg). The only possible spoilers MAY be in the comments which I haven't read. But the theory is interesting.

Now, I don't have any idea if the show is going in this direction at all, and the show portrays the WW in a MUCH more menacing and darker light. And I don't know at this point if there is even time to set up enough backstory between the WW and humans. But I've always found this to be a very intriguing theory and one that seems way more in line with GRRM's worldview and sensibilities than Jon and Dany ruling the Seven Kingdoms after banishing the WW and saving the day.
