What is consider human nature, are those things that are common in everyone human, which one does not have a choice in the matter (objectively established). Example: In order for you to live another day, you have to kill or have another living organism killed on your behalf. You are a predator, which is beyond your control.
Don't get me wrong, I see what you mean. This may be the case of an individual at the stage of infancy. But a characteristic also common in humans is, well, that they have
character. When humans grow to where they possess opinions, they then have defining qualities that make them unique.
Perhaps you would understand my point better if I provided an example:
By nature, humans are mostly carnivorous. However, due to the influence of their own opinions, some people become total vegetarians. This undoubtably becomes part of their
human nature, which considers not only objective biological qualities, but how subjective, individual opinion affects said qualities. The vegetarian is not causing a deficiency in their ability to survive, so their choice is still ethical, all the while proving that human nature is separable from reality in many individual cases. Since human natures differ, they are clearly not a reality, and cannot be a derivation for individual rights.
