The Borg Queen tells us in 'First Contact' that they seek perfection. What do they view as perfection? They assimilate every race they think would benefit them. "Your biological and technological distinctiveness will adapt to service us." She tells Data that he is an imperfect being created by imperfect beings so that means all the tech and biologicals they assimilate are imperfect in their opinion. What then is their idea/definition of perfection if they assimilate imperfection? Is there any explanation to this seeming dichotomy?
