Answer: Regardless of his android passions, David was already experimenting with the bio-goo, and he deliberately used it to impregnate Dr. Elizabeth Shaw with a proto-face-hugger in "Prometheus." In "Covenant," we learn that David later killed Shaw and is experimenting with her body because her body tissues contain human-alien antibodies that are essential to David's work (which is creating a new generation of xenomorphs).
