" the royal family are terrible and don't want humanity to ever leave the walls (Isn't that the whole point of fighting titans in the 1st place?),  "

Very excellent point, and this really struck me as well. Knowing what we know now, it seems safe to say that the Reiss family ordered the survey corps to go beyond the wall in bad faith in order to seem that all get killed and consequently act as a deterrent for the rest of the people from going outside. Who knows, in the recent chapter with the training instructor, we see the titans destroying the first outpost beyond the walls that was in the trees, maybe the coordinate holder ordered the titans to climb the trees and destroy the outpost.

We'll know soon enough what Grisha Yeager's plan was, he did manage to get the coordinate, but from what I've seen, I suspect he has been operating separately from the other homelanders, he might have another prerogative.
