The core formulation of law and our interpretation of morality is formed off of cultural cues. But our core moral instinct is biological and genetic.

This very example. This very topic is evidence to that fact. The moral conflict described as the topic of this HN article is consistent across populations across cultures. It is genetic. It is not learned.

In fact we can actually identify physical and structural difference in people who lack morals. Psychopaths, people who innately lack a moral sense. The differences can be literally seen as a physical manifestation of an actual 3D coordinate of the brain. A researcher who studies these things can actually tell you if you're a psychopath or not just by looking at a brain scan.
