Joe Carroll (The Following)
Highly intelligent with a smolder that could melt a steel bar. This man was charismatic enough to inspire a whole cult of serial killers who basically worship him.
Villanelle (Killing Eve)
Find something you love doing and you'll never work a day in your life. That is clearly Villanelle's mantra because she absolutely loves her job. Her electric chemistry with the equally obsessed Eve is something we'll never get enough of. When the day comes when someone orders a hit on us, we'd want it to be Villanelle who shows up on our doorstep.
Mary Ann Cotton (Dark Angel)
A true black widow who murdered her husbands so she could collect on their insurance policies. With the benefit of hindsight, we can see why men kept lining up to marry her despite the long line of dead spouses. What is a little death compared to the joy of waking up next to a beautiful, cultured woman like that?
Kilgrave (Jessica Jones)
The life of a serial has got to be hard given the cover-ups that follow every kill, but Kilgrave doesn't have to worry about any of that. That ample free time is probably why he always has perfectly coiffed hair and is able to pull off a purple suit with so little effort.
Kent Grainger (Wicked City)
He was officially nicknamed the Sunset Strip killer. His M.O is luring women into sexy situations before torturing and killing them. He wouldn't have been able to pull something like that off unless he had the looks and the charisma to match. His victim count is proof that he does.
Lovina Birdie (Damaged)
The lead character in this Indian web series who is totally incapable of feeling any remorse, you know, like a true psychopath. She barely puts in the work to identify her victims because people are drawn to her. She looks like someone you'd love to hang out with, until you don't, at which point it'll be too late.
