The Engineers; Good or Evil?

I really hope Shaw gets to their Homeworld, and things don't go berserk. Nothin' but friendly conversation. Friendly conversation and tea (pinkies up!). Seriously, though... Personally, i would find it super lame, if they end up being the antagonists. Which leads me to the whole subject of wether or not they want to destroy humans, and the fact that Shaw is content they are. I mean... in Prometheus, we saw ONE group of Engineers. Which could very well be a group of Outcasts, on their own mission to destroy humanity. Come on, now... it's a little moon with an Engineer base on it. Not their homeworld. I'd really hate for them to be the main antagonists of the series. Shaw/future characters should gain the knowledge they are seeking, and the story should move on from there. Yes, yes, i know... it would look like a happy Disney/picture outlook. But if anything, the Engineers' KARMA should be the main antagonist. The product of their wrongdoing should be the antagonist. The Xenomorph is just the tip of the iceberg in that department. I just like the Engineers so much. They're SO COOOOOOOOOOOOL! They're even starting to surpass the Predators, and i LOVE Predators. And that says a lot. it's starting to be Engineers > Predators So, what do you say, folks?
