I suppose you could look at it that it bigs Cersei up as the main antagonist
But in any story, its about the protagonist overcoming the antagonist. Its obviously more complicated in GOT because most of the characters have shades of grey, but I don't think anyone can argue that the Night King was ultimately the main antagonist because he was the enemy of every other character and had been built up from the very first scenes of the series 1. With that in mind, I think it's too early to kill him off half way through the last series, leaving other parts of the story to tell. And because he was the main antagonist I feel like it leaves the rest of that story a bit flat.
