Favourite gaming villain

Hermes from The Suffering simply because his voice actor absolutely nails it in a way that VAs today don't even measure up to. He is meant to be an unfeeling professional, who slowly begins to gain pleasure from his work to a point where he longs to know what they feel. Starting with simply staring at their bodies after, to listening to their final phone calls, to eventually putting himself in the gas chamber. It was and still is a very unique look at the "often tried and failed to achieve" sociopathic character type.

Favourite media villain so can be anime or western media

Fukase and Sera from Instant Bullet. I put both, because the story is constantly changing who is the villain and hero.

Sera is a completely broken person, who lacks the ability to actually feel any proper reactions to the world. Her father committing suicide around her doesn't even make her smile flinch, only asks when he is coming home. He had attempted her whole life to put some morality in her by making her obsessed with Sentai shows, which worked in that she became obsessed with being a hero. But being unable to actually understand morality beyond that simple black/white structure, and her power being literal control over bombs, she struggles to do anything but fail. She joins the Big Organization to hopefully get help in that regard, but their methods are so brutal she realizes she cannot escape and simply succumbs to being the villain.

Whereas Fukase, the protagonist, opens the story saying he will destroy the world and is the villain of the story. He is the pariah of everything, spends most of his days getting jumped and beaten, and hasn't had more than a handful of good memories in his life. He spends the entire runtime of the story being given a reason to live and being shown the beauty of the world. Getting friends, a new family, a girlfriend, all of it. Its almost a cliche rags to riches story. But by the end of it, instead of being grateful for any of it it simply enrages him further. He resents the world that kept it from him for so long, hates others who got it so easily, and is enraged knowing it will be taken from him again. So he reminds everyone, including the audience and Sera (who had been waiting on him the "hero" to kill her) that he is the true villain of this story and will absolutely destroy the world with his power.

Its a dynamic you don't often see, and its a shame it was cancelled resulting in the last volume being considerably rushed (leaving a lot of stuff unanswered, though the ending still works regardless).

Favourite historical villain

Karen Horney. A woman so egotistical and selfish she singlehandedly began the rot that infected Psychology while it was still in the womb. When Freud himself offended her by saying less than kind things about women, she just went "NO U" and made up her own field of things like "womb envy" that said men are destructive because they are driven mad by their inability to create life like the superior women. Her clinical work was also incredibly creepy, wherein she would become your "mother" and then re-raise you to be correct. This requires you to sign a minimum one year contract that you had to keep seeing her, under the guise of "it'll mess you up to stop half way."

Her work, and the lack of people criticizing it due to coinciding with the early feminist power push, is the foundation of why Psychology became a much more female oriented field and she is still held up as some high name by many in the field. And the abuse of Psychology as a political tool is half the reason why the Left ever had a chance. The Civil Rights Movement wouldn't have succeeded without the Doll Test. The media couldn't craft a narrative without shill funded "studies" to trick normies. Trannies needed John Money's horror show.
