I find it really strange you call humans the “absent/abusive parents” of the androids in this series. I don’t see any of that. Ash was believed by the humans in his crew to be one of them, which helped him to betray them. He didn’t have any gripes with humanity, he was just (like HAL) doing his job and regarding the crew as expendable. Bishop (who does appear in Alien 3 as well) was known as a machine, but quite well integrated into the squad. David has actually met his personal creator, Weyland, and Weyland seems to be more of a parent to him than his own daughter. David just decides from the beginning that he has superseded humanity.

Oram’s faith was mostly just there to make him feel insecure in his command, and that insecurity is why he decides to change course rather than order the crew (who were already disobeying him) back into cryosleep.

“Humanity” as a whole doesn’t try to fight off the xenomorphs. Most humans don’t know they exist, and the company keeps trying to obtain them. If you want to include Alien: Resurrection, even after the company goes under the government tries the same thing.

Oram’s decision to follow David AFTER finding out that David had fatally misled them about their safety from the creature is the one bit of unforgivable stupidity in the film. In contrast, I had no problem with Daniels. David had been attacking her, while Walter protected her, and when a one-handed person who looks & sounds like Walter shows up to protect her from the aliens, it seems entirely reasonable for her to conclude Walter (the more advanced model) won the fight and has rejoined her.

David doesn’t care about the corporation. He despises all of humanity.
