The neurotypical must cut out the dead flesh if they want to escape the parasitism of the psychopath. The psychopath does not care whom he leeches from. As long as their is benefit to be had for little in return, the psychopath will continue to suck their host dry.
This parasitism is usually nothing personal. It is not as if the psychopath is seeking retribution or revenge for sins that the target has committed. Simply put, the psychopath seeks to get everything for nothing. Whether it is the target’s pursestrings or their companionship, the psychopath is merely playing the part of a flesh eating disease: devouring everything in its path while giving nothing in return. The mosquito does not care who it bleeds dry so long as it remains full; the same can be said about the psychopath.
There are penalties for the psychopath once the host finally notices the blood loss. The psychopath is forced to move on to a new target. This can be a great inconvenience for the psychopath, especially if the parasitism was conducted on a close target – such as family – but it is the risk that the psychopath is always willing to take. The psychopath that is parasitic in the workplace can lose their job. Bleeding dry a significant other can cause the death of a relationship. However, the psychopath rarely cares. So long as their is something to feast on, she continues to devour anything around her even if there are eventual penalties for getting caught.
I believe that the psychopath feels entitled to enact such parasitism. With the narcissistic and self-centered tendencies she possesses, it seems automatic that others would be considered fair game, with few exceptions. In addition, she often feels invincible and invulnerable to any consequences that may arise as a result. The psychopath believes that others exist only to do her will and satisfy her goals. Others are tools, not human beings. Why would she not reap a harvest when she believes that there will always be a crop for the taking?
Even though there are penalties to the psychopath should the host cut out the necrotic tissue, he will continue to play the role of parasite. He feels entitled to do so and will, taking far more than he gives. It may not be anything personal, but if you want the blood loss and decay to stop, you must pull out your scalpel.
