Perhaps Renee and Draco were very close to Voldemort's ideas on this point, and felt that a hierarchical wizarding empire should be established. The wizarding world doesn't need equality! The interests of the nobles can never be violated!
Voldemort is not absolutely evil, and Dumbledore is not absolutely righteous.
So Voldemort here will not die in the ending, but Dumbledore and the Order of the Phoenix will definitely torture him. I don't like what they say.
Finally, Draco, I want us to be happy together!
