Why are so many of TV's bisexuals sociopaths?

BuzzFeed News

Killing Eve's Villanelle, played by Jodie Comer, is the latest TV bisexual who also happens to be a sociopath, joining How to Get Away with Murder's Annalise Keating and House of Cards' Frank Underwood. "Given the growing — but still small — number of bisexual characters onscreen, viewers might not be able to avoid internalizing the idea that bisexual lust and bloodlust go hand in hand," says Hannah Harris Green. "Annalise, Frank, and Villanelle not only embody these characteristics to a T they are such well-known and prominent characters that they have the potential to become iconic. Together they create a kind of new archetype for sociopathic bisexual characters. Their sexuality is explicit, not implied — setting them apart from many queer villains past. Not only are they amoral but they arrogantly prescribe different sets of rules for themselves — think of Frank Underwood justifying puppy murder to the camera in the first scene of House of Cards. They are unable to control their appetite — for food (Villanelle is obsessed with sweets, Annalise drinks vodka and can’t get enough ice cream, Frank eats ribs for breakfast), sex, or control. I don’t personally know any bi people (or anyone in general) who see themselves this way. But this trope lives on in Villanelle, whose sexual desire is very much linked to her need to kill."
