He exhibits many of the traits of serial killers. I suspect that his psychological profile would probably indicate that he aroused by his decisions that are directly responsible for the deaths of people.
He believes he is more intelligent than everyone and exhibits a godlike complex. There are many examples of doctors with this same personality type that were serial murderers.
He hides his murderous lust behind the bureaucratic protection of his role in government where he can carry out his form of killing while believing he is immune from prosecution by the cattle he believes he can so easily kill.
His modus operandi is quite literally using and abusing his bureaucratic authority to make decisions that determine if people live or die. He's able to kill and gratify himself without being caught.
Mass murderer. A serial killer does what the name implies. Kills one after another, serially. Fauchi kills en masse.
I believe the pathology in this context is the same as a serial killer albeit he is also a mass murderer. A mass murderer does not necessarily obtain gratification from their acts, I believe Dr. Fauci does, and exhibits other psychological traits common among serial killers.
I only address what he has done. Maybe pathologically / psychologically they are similar. IDK What he is, based on his actions, is a mass murderer. His murders were not committed serially.
He is a mass murderer, psychopath, sociopath, megalomaniac and a Sadist. Pure, distilled EVIL.
I think you covered all the bases. 😏
I just refer to him as “the genocidal gnome”.
