Keeping the Beast occupied, distracted, or amused, there are so many of them (they breed in litters), those controlling them have a real mess on their hands. That's one reason they have to keep them inoculated with the hive mind shot, ascension sky sail shot, with some fake happiness included.
Warning: though the Beast (including human types) smiles, laughs, and projects soulish love_far removed from Father's Divine Love, they will also murder you fast or slow if they are able, with similar smiles and laughs.
