I think that there is something greater than the Grimm, perhaps whatever created them or something, but I don't think that there's any form of hive-mind in place.

And the Grimm aren't exactly mindless. In episode 6 the Beowolves took there time in attacking Weiss, showing that they are a bit cautious when fighting Huntresses and then had enough sense to flee from the fire instead of chase after Ruby and Weiss.

Also, the Ursa in particular have shown quite a bit of personality. The Ursa Major also didn't seem to care so much about killing CRDL & Jaune so much as it wanted to get the tree sap they had.

The only instance of the Grimm working together thus far (aside from the Ursa pairs and the Beowolf packs) has been the Death Stalker and Nevermore kind of working together to kill Ruby. Even then it seemed more like coincidence that it went how it did.

Overall, I think that the Grimm are a destructive force, or at least used to be, but at the moment act just like animals; very violent, territorial, and deadly animals, but animal nonetheless.
