Complete Monster

""I met him fifteen years ago. I was told there was nothing left. No reason, no conscience, no understanding; even the most rudimentary sense of life or death, good or evil, right or wrong.""

- Dr. Loomis, Halloween

The Complete Monster is the most depraved of all characters; a villain utterly lacking in redeeming features. Trying to put a value on the evilness of a Complete Monster is like calculating the credit score of Bill Gates: it's a moot point.

Or, anyway, that is how the character is presented in the story. The character is a bad guy, full stop. The author has not taken the character through any actions toward redemption, or at least any that stuck.

The Complete Monster can be recognized by these signs:
 * The character is truly heinous by the standards of the story, which makes no attempt to present the character in any positive way. The character's terribleness is played seriously, even if the work is light and/or comedic. Other characters in-story must express fear, hate, and revulsion of this character.
 * The character has either no Freudian Excuse to validate their crimes, or their Freudian Excuse is presented in-story as inadequate. Any sympathy evoked in their backstories is long gone in the present.
 * They are completely devoid of altruistic qualities, show no regret for their crimes, are never redeemed or have any possibility of redemption.

Please note that a character crossing the Moral Event Horizon does not alone make them a Complete Monster. This trope isn't just about what the character does, but about what the character is. Their monstrous characters are reflected in their heinous deeds, which is what puts them a cut above the regular villains. And whatever their position, a Complete Monster has to go the full mile and meet all criteria: they are the worst they can possibly be in their role, in the space and scale they occupy.

Offscreen Villainy is advised against, with few exceptions depending on how clear the results of said villainy are.

Tropes Are Not Good; the Complete Monster can sometimes be indicative of lazy writing. A villain with no redeeming qualities can be viewed as exceedingly simplistic.

This trope is not Gushing About Villains You Like. A recurring evil character either has redeeming qualities presented as such within the moral framework of the story, or they don't. The Complete Monster may be a Magnificent Bastard or a Draco in Leather Pants to some audience members, but the completeness of their monstrosity does not depend on how well the audience receives them.

Compare Vile Villain, Saccharine Show, where the villain is noticeably more heinous than the other characters but is not necessarily a Complete Monster.

This is not a Real Life trope. Calling other people completely irredeemable is rude at best. Calling yourself one implies either a lack of understanding of the trope or severe mental illness.
