I agree with Denine. Jodi is a Psychopath.
The word "psychopathy" is a joining of the Greek words psyche ψυχή (mind, mental) and pathos πάθος (suffering, feeling).[5] The first documented use is from 1847 in Germany as psychopatisch,[6] and the noun psychopath has been traced to 1885.[7]
In medicine, patho- has long had a specific meaning of disease. Thus pathology has meant the study of disease since 1610, and psychopathology the study of mental disorder since 1847. A sense of "worthy to be a subject of pathology, morbid, excessive" is attested from 1845,[8] including the phrase pathological liar from 1891 in the medical literature.
Psychosis was also used in Germany from 1841, including in a general sense of any mental derangement. The suffix -ωσις (-osis) meant in this case "abnormal condition". This term or its adjective psychotic would come to refer specifically to mental states or disorders characterized by hallucinations, delusions or being in some other sense out of touch with reality.[9]
The term psychopathy initially had a very general meaning too, referring to all sorts of mental disorders. Some medical dictionaries still define it in the narrow and broad sense, for example MedlinePlus from the U.S. National Library of Medicine.[10] Others, such as Stedman's Medical Dictionary, define it only as an outdated term for an antisocial type of personality disorder.[11]
The slang psycho has been traced to 1936 as a shortening of the adjective psychopathic, and from 1942 as a shortening of the noun psychopath,[12] and it can also be short for psychotic.[13]
The label psychopath has been described as strangely nonspecific but probably persisting because it indicates that the source of behavior lies in the psyche rather than in the situation. The media usually uses the term to designate any criminal whose offenses are particularly abhorrent and unnatural, but that is not its original or general psychiatric meaning.[14] In the alternative term sociopath, socio has been common in compound words since around 1880, referring to social or society.[15]
