Foolkiller (Marvel Cinematic Universe)

"You were given every advantage; allowed to make mistake after mistake... and just like Donny, you never worked hard or made any effort to improve. It was handed to you! No longer..."

- Sallinger to Erik

"Evil's the wrong word. I am asserting fairness in an unfair world! I'm vengeful without pity... appropriately cruel! Those are the things you're sensing, not evil!"

- Sallinger explains himself

"All I am is a man with my feet on the ground and a brain in my head. And yet, I can bring pain to power just by getting close. I have the only superpower that is not a fraud, because it was evolved through sheer human pain. And that is extraordinary. Because it's real."

- Sallinger torturing Erik

Gregory Sallinger is the main antagonist of Jessica Jones season 3. He was a highly skilled criminal mastermind and serial killer with high-levels of intelligence, violent tendencies and an obsession with killing Jessica Jones.

He was portrayed by Jeremy Bobb.

Past
Sallinger grew up together with a brother, Donny. Both wanted to be photographers but while Sallinger envisioned himself as the true artist and considered his brother as dumb and incompetent, their father favored Donny. After Donny died in a suspicious tractor accident, Sallinger hoped that their father would be more favorable towards him but his father only claimed that he wished it was Sallinger who should have died and stabbed him during the funeral dinner.

Sallinger eventually turned into a psychopathic serial killer in New York City, targeting people who he tought did not deserve whatever they achieved in life. He made a habit of confronting them with their "crimes" and misdeeds in order to capture the moment they realized their errors on photograph. Thriving on their misery and fear, Sallinger would then kill his victims, cut them up and drop the bodies in a sewage tank underneath a train yard. He kept the photos of his victim in a hidden slot behind his bureau.
