I have watched this one many times now. I also had many unanswered questions like why scientists/astronauts would do some very dumb stuff?
Viewers need to realise a few things, and the whole movie falls into place.
1 The entire purpose of the trip was to find the Aliens that made life on earth. Weyland did not want to die (old age). " If they made us surely they can save us" Only a few were aware of this (David, Vickers & perhaps other Weyland Corporation crew on board)
2 Old man Weyland was prepared to do anything, sacrifice the others to get what he wanted. This he did through David, whose primary objective was to Weylands agenda.
3 Vickers, Weylands daughter, wanted Weyland dead. He was old. Him dying was the natural order of things. She would then be Head of Weyland Corporation. But Weyland didn't want to die, and didn't want a daughter to be heir to his empire. He wanted a son, but didn't have one, and he made robot David yo be his right hand man. Much to the disgust of Vickers.
The hired scientists were really just a bunch of naive ones, each chasing their own agenda eg Money, getting paid at end of mission. They were not astraunots. Non of them knew why they were travelling in space ship for 2 years, or where they were going (except the archaeologists) That's why they made and acted on very stupid decisions in space. Eg drinking alcohol, taking off helmets, walking in sandals, smoking weed, trying to be friendly to an alien snake...
4 Weyland was willing to sacrifice all these scientists people to get what he wanted eg by allowing David to experiment on Charlie, allowing an alien fetus to grow in Elizabeth. He basically authorized David to do as he saw necessary to get the results.
5 Unfortunately the level headed people were also killed off, eg Vickers and the ship's captain and assistants. The rest of the crew deserved to die imo.
