I've always wanted the First Order to be wagging their fingers at the Republic, trying to scold them and stop them from being corrupt and greedy. Obviously that is not the case, as thus far (based on VII) they are very much the villains of this trilogy.

I would love to see the FO splinter into two groups. A group led by Snoke that are villains, out to destroy and take over the galaxies. And another group that are just trying to represent a different view, to represent their people, so they can have their own equal standing alongside the Republic. Two parties, somewhat like Democrats vs Republicans, working for the greater good of the galaxies(universe) (or country).

But that will never happen. The First Order as a whole will remain villains.
