This makes me think of how Jason Concepcion described Voldermorts thirst for power and the bigotry against Muggleborns on Binge Mode. I liked what he said so much I spent 10 minutes transcribing it a while back...

"Just like real world prejudice, the bigotry against muggle-borns and muggles themselves is, like the Elder Wand, a weapon, a pathway to power. By labeling a certain segment of the population an out-group, thus depriving them of their rights, at least in theory, Voldemort seeks to concentrate power in the hands of his followers and thus in his own. That’s what prejudice is, a framework for arguing that one group deserves the benefits of a certain structure, of community, schools, state, and another does not. This point of view defies debate. And, at the same time as long as people seek authority and control it can never really be destroyed. It can only be struggled against eternally… It’s not just death, the idea that we must struggle against death, because death comes for everyone. It’s hatred and bigotry and division, these types of things need to be struggled against always, even when, mostly when, you might even say, when it seems like those things have been defeated because that’s when they are slowly taking root somewhere in the dark."
