Access to reasonably affordable healthcare is one of the foundational pillars of any society. If you actively undermine that pillar for your own personal gain, you are dissolving the bonds that hold society fast. You are killing society. Perhaps sociopath is the wrong word because it has a very specific meaning in the medical lexicon. The word I am looking for is one who actively and directly kills the society around him, seemingly with no remorse. Parasite doesn't work because a parasite kills an organism external to itself. Intensely greedy comes close, but also falls short. Any ideas?
