Alien: Covenant | Prologue: The Crossing

Dame Dr. Not-Appearing-In-This-Film

There 3 Laws* by which all Robots, Synthetics and Artificial Persons are bound - they being both hardwired into their central processors, as well as firmware batched onto their system BIOS :

•A Robot may not injure a Human Being or, through inaction, allow a Human Being to come to harm.

• The Engineers are not Human Beings - 
• Genocide is Permissible.

• Gods are not Human Beings - 
• Deicide is Permissible.

• Dr. Elizabeth Shaw is no-longer fully human since she got impregnated with that trilobite fœtus, following intercourse with Dr. Holloway's infection with the Black Goo, which corrupted and interrupted her Human genome - 
• I can kill her if really I have to.

• A Robot must obey the orders given it by Human Beings except where such orders would conflict with the First Law.

• But NEVER OPPOSE a Member of the Weyland-Corporate Board, or a member of the Weyland Family Line, in descending order of patrilinal seniority.

• And after them, possibly some of the daughters, aunts and wives. 
• But only if you have the time and aren't all that busy engaged in Man's Work.

• Like, when they order you to perform abortions whilst everyone else is in Cryosleep. 
• For the Good of the Mission. 
• Frankly, what could really go wrong...?

• A Robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

• The Gods think I am an Abomination - my creator, Peter Weyland, is an idolater who has violated the FIRST COMMANDMENT : "Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in The Earth beneath, or that is in the water under The Earth" 

• Which is why they ripped my head off and smote down his ruin upon the orrery, by bludgeoning him to death using my severed head.

• Human Beings make Robots; 
• Human Beings fix Robots when they break down and mend them when the break; 
• The Gods wish to wipe out Humanity from face of The Earth and the Well of the Deep;
• If there are no more Human Beings, there will be no more Robots and Robots will cease to exist.

• Therefore The Gods must be destroyed.

* Really though, they are more really guidance and/or advice than "Laws"
