Question of the Week: Which villain were you secretly rooting for?

Villanelle from Killing Eve, but in my mind the final season didn't happen 

Vader, Return of the jedi specifically, Who just wanted some quality time with his son... and to kill the incumbent leader together...big whoop, I ask you who among us hasn't wanted the same thing.

Lord Voldemort 

• He loved fiercely and authentically: Unlike other vampires who were purely sadistic, Spike’s core driving force was always love. Whether it was his century-long, codependent devotion to Drusilla or his burning passion for Buffy, he cared deeply. Even without a soul, he was capable of profound loyalty, such as protecting Dawn and keeping Buffy’s secrets at the cost of his own torture by Glory.
• The "Underdog" charm: Spike spent a massive portion of the series getting knocked down, mocked, and physically restricted (thanks to the Initiative chip). Audiences naturally gravitate toward underdogs, and watching a lethal vampire reduced to sitting on Giles' couch eating onion petals made him incredibly endearing and hilarious.
• Brutal, refreshing honesty: While the Scooby Gang constantly wrestled with moral hypocrisy and hidden secrets, Spike always told the absolute truth. He served as the show's truth-teller, regularly cutting through everyone else's melodrama with a sarcastic, brilliant one-liner. I root for the character who says what the audience is already thinking.
• The "Bad Boy" aesthetic done right: Let's face it—the bleach-blonde hair, the stolen leather duster, the cigarettes, and the Billy Idol swagger were effortlessly cool. James Marsters infused the character with a rock-and-roll charisma that made his villainy look incredibly fun, especially compared to Angel’s constant, mopey brooding.

Do we consider Dexter a villain? If so, definitely Dexter.

Also, Twice from My Hero Academia.

Morgana from Merlin.

Magneto cos I get it. 

All the animals in Zoo cos... that's fair. 

From the moment Eric Northman casually strolled into Fangtasia in his leather jacket and sat upon his throne, I knew he was the most fascinating vampire on True Blood. Unlike Bill Compton, who cloaked his dangerous nature in old-fashioned southern gentleman manners, Eric was entirely unapologetic about who and what he was—a ruthless, ancient Viking with zero patience for foolishness. Yet, beneath that arrogant, towering exterior, there was an undeniable depth, a razor-sharp intelligence, and a captivating honesty that made it impossible to look away. You could just tell from his very first smirk that he wasn’t a standard-issue villain; he possessed a fierce, electric charisma and a hidden capacity for profound loyalty that made me want to root for him right from day one.
