Villanelle may sometimes be described as a sociopath due to what she dies, and sometimes she may display traits that may make her a psychopath, but these quotes of hers show that she is not a sociopath or a psychopath because she reports to feeling things, some of which are interpersonal in nature, and that is not something that may often be seen in sociopaths or psychopaths. Villanelle has been seen to say that, "I feel things when I'm with you." Villanelle has also been described as "a manic pixie dream assassin who's as charming as she is psychopathic", and a  "chillingly relatable monster" who takes "fulsome pleasure in a murder well performed".
