hmm....i feel it goes against the Predator's personality. It's been set up he seeks out worthy opponents to best in battle - hounding them to the point of exhaustion doesn't make sense to me. it's make him also like a deer hunter just shooting around a deer and making it run in terror all over the place beforethe kill - where's the honour and battle skill in that? it's more of just mindless sadism, which doesn't fit the Pred's profile at all.
If you look at the original movie the Pred doesn't really come across as honourable at all. He only spares unarmed humans because they're 'No sport'. I'm guessing he'd have shot Anna if Arnie hadn't kicked the gun out of her hand. I think its because the character was so well accepted that fans/comic/book writers put the honour code into the mythos, but that wasn't the original intention. It was a story about humans being hunted by something as cruel as us but with greater technology. P2 showed the respect thing at the end which opened up the character, but P2 was really based on the creature Stan Winston designed not the original concept the writers had for P1. P2 is still pretty cruel, he taunts Glover with the necklace showing he could have easily taken him out at the cemetary.Also i have always had a problem with this, for a race that's so honourable you'd think he'd have the decency to die like a true hunter not setting off a small nucular blast killing himself whilst trying to pop a cheap kill with Dutch at the same time.
I know you could say he was making sure his body was never found and honouring his race by doing this but i still found it a little cheap. He even mocks Dutch by laughing whilst doing it!!
about the bomb. its not that he was trying to get the last kill in or anything like that. This is an interstellar hunter whose technology is far superior to ours. He kills himself because A)doesn't want the technology to get captured and he doesn't want his body to be left behind. I think he laughs because there was no fear of death.
Just what i have always thought.
