Contrary to what most of the people believe, the Draka were not collectively psychopaths, sociopaths. They didn't have narcissistic or sadistic personnality. And, they were not "mad" either.
Draka who had mental illnesses or disabilities were not well treated, by the way, but that's another topic.
The Draka did have ethics. They respected the State, and were ready to gave their lives for the State. They put their own Serfs through hell to ensure that they never rebelled, and it was done for their own personal good as well as the good of the State.
They didn't do anything to their Serfs. They did what was necessary to control them, no more, no less. Except for the "punchbag slaves", of course.
Some espoused a paternalistic view, as well. This view can be summed as "How the inferiors would be able to live, if we weren't there to guide and protect them, from their own nature ?".
Basically, their attitude could be compared to a farmer's attitude, who is firm, but fair and "loving", to his animals (who he will still kill if needed).
Draka Citizens respected other Citizens. Some of them even respected the non-Draka European Whites, seeing them as fellows. Emphasis on "European" (white-passing and fair-skinned people who were not purely European in origin were not white), and on "White", which didn't include the Jews and Gypsies to them. There were also debates about the "whiteness" of the Italians, Spanish, Portuguese, Greeks and Slavs. Some Draka saw them as European, hence Whites. Some Draka saw them as "mixed" (with Arab, Turkish, Chinese, Mongol... blood), "less civilized" and "weak".
The point is, the Draka Citizens respected each other, and sometimes other Whites, as their racial equals. They were always polite to each other, and gave a special respect to older people and veterans. There were competitions between Draka villages, cities and regions, especially sport competitions. But it was always respectful. There were never, for example, Draka hooligans. When there was a fire, a hurricane, a tornado or any other natural disaster, Citizens fought it together and supported each other. Finally, Draka-on-Draka crime was nearly not existent.
Draka couples or families were the most egalitarian and respectful in the world. Any kind of abuse (sexual, psychological or physical) was forbidden and frowned upon, mostly thanks to the Amazons and other feminist groups. Husbands, wives and children all respected and supported each other.
Women weren't forced to do the housework, either.
The only exception was when a children was disabled. Said children became a burden and a shame for the family, unable to meet expectations (from family members themselves and outside society). Moreover, since the Draka associated their own "Master Race" with superiority and strength, they always suspected that disabled children were not racially pure, that there had been miscegenation. The result was that disabled people were almost everytime rejected by their families.
People had to marry and have a compulsory number of (non-disabled) children, but it was completely accepted that marriage did not necessarily equal love, romantic or sexual attraction, or exclusivity. Extra-marital relationships (sexual, romantic or both), homosexuality and bisexuality were accepted.
Draka families could be awesome to live in. But of course, it was the Serfs who paid the price : they did the housework, and they suffered all the abuse.
