If two predators act stupidly and waste their time with humans and posing around when they should be trying to keep track of Aliens, of course they're going to die. What would have been "beyond gay" was if those two creatures had survived. And if you want Aliens to be easily killed, then your'e going to dilute the Predator. The Predators consider them the most challenging prey in the entire galaxy, which is why they use them as a rite of pasage. If they can kill them easily, then it makes a mockery of their own rite of passage, which you shouldn't want.
