[Predator] What exactly is Yautja culture like?

I understand they put a LOT of emphasis on hunting, but what exactly does their culture say about it? Is it a passtime? A rite of passage? A necessity? I want to know why the obsession with it.

The Yautja hunt the most dangerous life forms as a source of honor and prestige. The females of the species (who do not participate in hunts themselves) apparently regard skilled male hunters as highly desirable mates. 

The City Hunter in Predator 2 appears to be a youngster finishing up his first hunt in a possible manhood ritual of some kind, but the Jungle Hunter in the first movie is apparently more aged and experienced, hunting with no assistance in an environment with comparatively more natural threats. 

Failure in the hunt seems to mandate suicide; this might be a ritual to cleanse shame, or an attempt to prevent their technology from falling into the wrong hands, or something else. 

Hunters are expected to seek out worthy, challenging prey; they will not target children, the defenseless, or even recently pregnant women (so they're also pro-lifers?). In a typical hunt it seems that they will target multiple individuals and harvest trophies from the most prized catch; the others are skinned and left hanging, possibly to indicate they were not worthy prey, or at least not a big enough challenge. Xenomorphs are apparently considered an especially challenging prey, with xenomorph hunts being led by skilled, experienced veterans. 

"Predator**s**" introduces a trio of black-clad Predators who are apparently dishonorable by the standards of other Yautja; we don't know exactly why, but they do use different hunting tactics, like smuggling humans offworld for hunting on a preserve, and using more sophisticated technology.

Or you can believe the newest movie and say they're harvesting DNA from the trophies,  to use as genetic enhancements to improve the species. Whatever.
