Eugenics is a set of beliefs and practices that aims at improving the genetic quality of the human population through some set of desirable traits chosen as the parameters. It is a social philosophy advocating the improvement of human genetic traits through the promotion of higher rates of sexual reproduction for people with desired traits (positive eugenics), or reduced rates of sexual reproduction and sterilization of people, and even potentially to exterminate people that are considered less-desirable or with undesired traits (negative eugenics), or both. Alternatively, gene selection rather than "people selection" has recently been made possible through advances in gene editing. The exact definition of eugenics has been a matter of debate through many different groups since the term was coined. A major criticism of eugenics policies is that, regardless of whether "negative" or "positive" policies are used, they are vulnerable to severe abuse or lack of ethics, because the criteria of selection are determined by whichever group is in political power. Furthermore, negative eugenics in particular is considered to be a violation of basic human rights, which include the right to reproduction and to exist freely.
American Roots in Nazi Eugenics
The Black Sun Program behind Hitler and his henchmen victimized an entire continent and exterminated millions in his quest for a co-called "Master Race."But the concept of a white, blond-haired, blue-eyed master Nordic race didn't originate with Hitler. The idea was created in the United States, and cultivated in California, decades before Hitler came to power. California eugenicists played an important, although little known, role in the American eugenics movement's campaign for ethnic cleansing (murder). Eugenics was the racist pseudoscience determined to wipe away all human beings deemed "unfit," preserving only those who conformed to a Nordic stereotype. Elements of the philosophy were enshrined as national policy by forced sterilization and segregation laws, as well as marriage restrictions, enacted in twenty-seven states. In 1909, California became the third state to adopt such laws. Ultimately, eugenics practitioners coercively sterilized some 60,000 Americans, barred the marriage of thousands, forcibly segregated thousands in "colonies," and persecuted untold numbers in ways we are just learning. Before World War II, nearly half of coercive sterilizations were done in California, and even after the war, the state accounted for a third of all such surgeries. After the war, eugenics was declared a crime against humanity--an act of Genocide. 
The term directed evolution is used within the transhumanist community to refer to the idea of applying the principles of directed evolution and experimental evolution to the control of human evolution. This has its base in Eugenics theories.
German Esoteric Societies
The inner core of the Thule society were Satanists that were practicing Black Magic. The sole intent was for them to, with help from magic rituals, bring Consciousness to a level where they could perceive the evil of the world and stay in telepathic communication with Negative Aliens who communicate on that level. With the help of this dark energy, the goal of the initiated would be to create a race of Supermen of Aryan stock, who would exterminate all “lower” races. (see Eugenics)
Class Struggles, Marxism
These class struggle ideologies are the basis of Collectivism and eugenic theories, which fundamentally make up atheistic forms of Socialism and Communism. These are easily corruptible governmental structures that fully support victims and victimizers, where there are absolutely no protections for personal liberty or individual freedoms. Individuality and the ranges of unique group expression are not recognized as a valid identity in one centralized power governing a global controlled society and thus, Individualism, Autonomy and Self-Leadership are not respected or allowed to be expressed under its oppressive tyrannical social control. According to collectivism ideologies like Communism, an individual’s life is not their own, but belongs to the social group and has no rights except those which that society permits him to enjoy.
