that's very much complicated by Draco having been raised to be a sociopath

I need to object pretty strongly to this particular phrase. Draco is not being raised to be a sociopath; he's being raised to be a high-status member of a hierarchical society. Draco and his father very much love each other, and are perfectly capable of making real emotional bonds with people that they have identified unequivocally as 'pack'. EY has actually done very well at showing Draco as what a perfectly normal child becomes in that environment.

This is an important distinction, because we need to remember that 'sociopathy' is a comparatively rare (and usually inborn) condition, while high-status machiavellian narcissism is a natural consequence of human evolutionary psychology.
