Philosophers have already identified the problem. There is no universal standard of morality or ethics.
The core of ethics derives from evolution. Societies with certain sets of cooperative and competitive values destroy, dominate, and expand. Mutations are constantly happening and some of those ethics can lead to the self-destruction of a culture, while some make a culture even more dominant. Some are neutral and just background noise and have no substantial impact on the society.
In the grand scheme of things the only thing that matters for morals and ethics is whether the culture that embodies those ethics can survive against pressure from other cultures.
Some ethics have been selected into the genome as they provide superior fitness of individuals.
The idea that we should pursue equal outcomes is a mutation. In general it has been shown to destroy a culture (socialism) when competing with more capitalistic cultures. The victim type culture is likely to be much weaker than one where people constantly compete to rise to the pinnacle of power and wealth.
Ultimately power and wealth drive innovation; and innovation, especially of weapons, drives domination. There are other types of domination, such as media, food, language, etc.
