David is truly the alien.

Karstenphd, yes he is a devise with the capability of unlimited destruction.

David is by design, a sociopath, guided by the constraints of whom is in charge of him. He is sterile in regards to emotion and would exhaust the same "feelings" if he were opening a stick of gum for someone or wiping out a planet.

Two things that most assuredly affected David's task were Dr. Holloway in saying "anything and everything" at the pool table and the removal of his head. And maybe Vickers threatening to cut his cord too.

Dr. Holloway removed limits to the scope of David's quest for how the black goo works and David's self-preservation embedded instinct most likely took over when the Engineer pulled off his head. And then it was so very the time to wipe out the Engineers after that. They messed up his hair.

I just love him. He spends 39 light years learning the root of every language, monitors the processes of the Prometheus ship, watches your dreams, and still has time to bleach his roots.

Ha, Ingeniero, Priceless! :-)

ingeniero, he went to all that trouble to look good for the crew waking up n not one of those ignorant cretins complimented him on his hair, that's what started this whole thing.

iv always believed that david will save or at the very least try and save the day. obviously thatl be in a future sequel but I think he will look for redemption

@ali81 are you saying David has self esteem issues! I was trying to fit in "head and shoulders rage Engineer shampoo™ with Ingeniero's head shot but ....

The synthetic Roy Batty in Blade Runner seemed to develop a soul prior to his expiration and I was not expecting that so maybe we'll get thrown for a loop...

yes, hes made a genuine attempt to pretty himself for the crew and not one of them took the time out to comment on it. they got what they deserved imo.

I think roy is one of the greatest android portrails in movie history. his death scene is iconic and the releasing of the dove is done brilliantly. all credit given to the actor for that as he came up with the lines. I think david is in essence a rebellious teen. hes been given free reign to do what he wants. so he does. he knows when he is being mistreated and reacts in the manner he believes humans would, but feels nothing. he has been mistreated by both humans and engineer so now he is free, as weyland is dead, he cares not for either. but that teen at some point grows up and learns the error of his way.

So what do you think this rebellious teen is going to do when he's introduced to his twin brother for the first time?! Rotflmao

at this stage I think he could go either way here but I think hel try and manipulate walter. hel see walter as a back up, esp if he is able to somehow download himself or at least in some part into walter incase something should happen to him.
