Pure Evils who are in a position of power and regularly abuse their authority. There are many examples down below.

• Police Officers or Detectives usual goal is to maintain the law and order within areas they work in or solve crimes if more advanced, but some can either go too far with their acts or could be the ones committing crimes (e.g. Jo Slade, Frank Tenpenny, Samuel Norton (Film), Howard Payne, Light Yagami, and Manny Pardo).
• Government Agents who either work for the government or are the entities related to them who abuse their powers in order to enforce whatever order they wish in certain places (e.g. Agent Trout, Daniel Harper, and Agent 23,).
• Military Members whether fantasy based or not that serve for corrupt armies, most often because whatever terrible government they pledged their allegiance to had ordered them so (e.g. Major, Shan Yu, Griffith/Femto, Amon Goeth, General Mandible, Captain Vidal, and Cobra Commander). They mostly fit as Dark Knights or Warlords.
• False Superheroes, whether they are fallen heroes or supervillains pretending to be heroes, they will do anything, even working within the laws to achieve their goals (e.g. Black Noir, Mysterio, Syndrome, Black Beetle, and Professor Zoom).
• Politicians who either work for political parties or by themselves and most often, will hold some kind of political power over a population, depending on the story (e.g. Quercus Alba, Adam Sutler, Frank Underwood, Pa Tee Tint, Chairman Drek, and Vice-Counsel DuPont). They are a common position for corrupt official villains as they can be totalitarians, tyrants, oppressors, propagandists, leaders, corrupting influences, tyrants, control freaks, and so on.
• Lawyers who are mostly well versed in either a fantasy, sci-fi, or realistic world, usually upholding the rule of law and ensure that individuals have access to justice but there are some who do exploit loopholes to commit crimes or aid criminals (e.g. Manfred von Karma). Many are serious crimes.
• Judges that are supposed to be fair with the laws can sometimes falsely accuse someone of a crime they didn't commit just to satisfy themselves in their own way of twisted justice (e.g. Judge Claude Frollo, Judge Doom, Judge Holden, Judge Turpin, and Thomas Danforth).
• Businesspeople or Ceo's who usually work or perhaps own businesses or corporations that are going to be involving evil schemes to the table (e.g. William Afton, Patrick Bateman, Poppy Adams, Frank Underwood, Dominic Greene, and Big Jack Horner). They can also be the main boss and have employees have their pay smaller for something personal or can also be a high-ranking employee of those companies.
• Doctors and Scientists who are normally supposed to heal others or research anyways of saving more lives in certain crisis but there can some who are involved with fraud or corrupt enough to think about taking over the world, depending on the setting. NOT ALL OF THEM are officials. However, there are some who are working for corrupt governments or highly powerful organizations and usually for self-centered reasons (e.g. Dr. Gaul, Professor Hojo, Marcus Andrews, and Judy Reyes).
• Spies or sometimes called secret agents and so on who watch and gather information on them without their targets knowing, using espionage and other dirty tactics to achieve their own goals (e.g. Ben Childress and Willaim Rawlins (Marvel)).
• Religious leaders that can be either; priests, rabbis, shaman, imam, monks, ministers, cardinals, popes, reverends, clergy etc... They use religion and faith for their own devious and evil purposes, some can also be members that only use the word of whatever god they believe in, depending on their faiths and religion it can vary, as excuses to get away with corrupt actions. (e.g. Cardinal Sin, Judge Claude Frollo, Mohg The Lord of Blood, Mola Ram, Dr. Facilier, Bishop Ladja, The Lich, and Aamon)

Corrupt Chiefs can also qualify since they too can rule a nation in certain eras.
• Aristocrats while not as powerful as members of the monarchy, they do hold some kind of power over certain people working for them either in their own personal lands or large properties they own due to the permission of their boss. These includes Baronets and Baronetesses, Knights and Dames, Lords and Ladies (High ranking ones), Barons and Baronesses, Viscounts and Viscountesses, Counts and/or Earls and Countesses, Marquesses and Marchionesses, Dukes and Duchesses, etc. (e.g. Lord Cutler Beckett, Godrick The Grafted, Lady Van Tassel, Fractos, Mr. Barron, Count Dracula (Bram Stoker), Dandy Mott, and Kefka Palazzo)
• School Staffs be they teachers, principals, prominent students, or admins of the school who use their position of power to violate student rights or mold them to the ways they want the students to become when they grow up.
