   General info

While it is hard to know for sure how the predator society function and whether they have morals as we know the term, it appears to be obvious that they at least have a very strong code of honor and that they take great pride in their strength and conduct.

The predators hunt only worthy prey, meaning anything that is capable of fighting back or at least defending itself. It seems to be below them to kill the weak or the young, and if they meet a worthy strong opponent that has managed to fight back, they usually honor that opponent with lowering their weapons and fighting them in hand to hand - or blade to blade - combat.

They also seem to have a strong sense of respect. In the end of Predator 2, not only did the group of predators respect their leader and act on his command, but they also showed great respect to the human prey who managed to kill one of their own.
