There four classes of beings in the story.
The first one belongs to the Priestly Class who attends to matters ritualistic and spiritual, like Creation of Life.
The last one we saw in the movie belongs to the Warrior Class, hence his hostile attitude and his armored exoskeleton/suit.
There may be a Kingly Class, or some sort in the sequel which may or may not get made. I hope it gets made.
G-d is a being above all these four classes and yet to be revealed.
Or they just might scrap this idea altogether, and just use 2 classes, Priestly King/Philosopher King, and slaves who consist of both warriors & engineers (likely the one in the hyper sleep chamber)
