Engineer doesn't immediately attack after getting up from sleep - what pisses hi

I think that the Engineer pilot gets angry becouse the Vessel is a weapon of mass destruction so the Vessel is prohibited for another races instead of engineers. So he immediately gets angry for they are been there. And he understands that they are interrupted his sleep, and awakens him. Maybe the engineers has some kind of code or hierarchy system. On the opening of the film, the engineer sacrifices himself, maybe he was been ordered to do so. I think that in the culture of engineers, no one is allowed questioning the orders for searching reason is prohibited. If ıt is true, than the Awakened Pilot Engineer is gets angry for he is been questioned. Shaw questioned him for the reasons that creations of Black Sperms, and the Urn Silos.. It seems that the Engineer also understands the language of Humans (including English) but he also understands that the droid does not ask the way that Shaw did. David exacly translate the Weyland's question; "The immortality"... So if it is the case, then the Engineer pissed of against them for their ignorances. And the last point he realizes that the David is also a Droid. So maybe the Engineer wants to punish them for Humanity's achieaved technology level. That is the reason for the name of "Prometheus" Becouse in myths the Prometheus is punished for sharing the secret technology of gods for humans. And the gods punished him for his ignorance. I think that this is the main reason for the Engineer Pilot getting pissed-off... But Shaw's other questions never answered on the film. If the Engineers created the Humanity just like the beginning of the Movie with sacrifice.. Then it is completely out of reason that why they are try to wipe-out life on earth? I think there is a war with another technologyc civilisation maybe like Predators (Youtjas), for that they are also pictured in AVP for some kind of gods on earth. The Engineers is also a god becouse they spread the life on earth. And so there is a war between them. Maybe it is the reason that in Predator 2 movie the Predator's ship contains a collection of rotted skulls of Engineers. If it is the case, than maybe the Engineers does not want to wipe-out earth from life.. Maybe they simply choose the Earth as "Warground" against with Yotjas ....... There is so much things unanswered on Prometheus, but I think that Prometheus is just a beginning.... ;)))))))))))
