QuoteUnless we naively believe the Predators to be a one dimensional race it has to be for both, and probably many more reasons. I would imagine that they hunt for all the reason we do: sport, ritual, food, materials for the production of clothing and other items, etc.
In P2 the predator went to the slaughterhouse to eat, so I quess when they are on earth they hunt for sport, if their "code" is involved, that makes it a ritual.
So I would quess both.
