Tribal crap is all hogwash, as far as "tribes" go. The preds are an advanced species, in any advance species there are groups of different kinds, and different individuals.
Some hunt alone, some like to hunt with their pals, or on "charters" if you will. You know, like when a bunch of strangers meet on a safari or fishing trip...
The hunt is not a general reflection of their society at large, although it is possible it represents a significant portion of it, or some form of recreation enjoyed by a large segment of the population.
That said, these interstellar safaris are probably only enjoyed by the upper-crust, just as large populations around the globe enjoy recreational hunting, but only a select few can afford the 50k dollars it takes to get an elephant permit.
Fitz is talking something half-sensical.
