The larger theme of Westworld is positing that the relatively anonymous shadow self that acts as a sociopath and psychopath is our real self. The person unhindered by morality who becomes essentially an Ubermensch in Westworld is above Good and Evil and godlike.
Westworld then becomes the natural extension of Internet pornography save it involves some of the androids suffering decades of trauma.
Who then is more human, the visitor to Westworld, or the victimized android who is gaining sentience?
It's very dark. In a way, Westworld is an anti-morality play in which God is a cruel deity who plays with us in our suffering and then we are free to reject our creator/tormentor.
AI is a colossal error, and one that we should be more fearful of than nuclear war.
