What I am referring to are the innate intrinsic features embedded in the DNA of humans via evolution.
The "Do not kill other humans" innate program in the human brain is as basic as the 'will to survive' the hunger, sex, need to breathe' instinct and other primal instinct. The moral instinct is different in the sense, it is no so obvious as the others and it is unfolding slowly.
These are innate and intrinsic [nature] so has nothing to do with cultural or nurture.
To flesh out your claim, for instance our being vertebrate mammals is "innate and intrinsic [nature] so has nothing to do with cultural or nurture".
Looking at other vertebrate mammals we see other vertebrate mammals besides man are genetically programmed to have transmissible cultures . These are largely transmitted via individual animal mothers to their young. It is therefore probable that humans too are genetically programmed to have some transmissible culture of belief and practice. There must therefore be the genetic possibility of some non specific cultural pattern for animal mothers to teach their offspring what to do and what not to do whilst the said offspring are puppies, kittens or cubs.
There are unusual happenings among vertebrates where adults learn from others and may be said to have acquired a novel cultural pattern. Chaffinches change their songs according to what surrounding chaffinches are singing. Parrots, starlings and mynahs too can do this too. So some cultural specifics are plastic .
Where your thinking on the matter is incorrect is that vertebrate mammalian species' non=specific cultural ability and function is the same as specific cultural codes. Man alone has specific cultural codes. The items of those are commonly enshrined in religious codes such as Leviticus and popular belief systems such as are today personalised by popular celebrities who include among their ranks singers, politicians, actors, royal personages, and even criminals.
For all intents and purposes only man alone has a history of ideas. "Must not kill other humans" is an item, a detail within a specific cultural code or set of cultural codes; it is not itself genetic but cultural. History of ideas can be picked up from a proper study of history as an academic discipline.
The notion "Must not kill other humans" is genetically programmed is dangerous. We are at a most dangerous time and "Must not kill other humans" is a civilised injunction which is itself in danger. We must not rely on genetic programming to save us from disaster.
