According to the Star Wars universe, a Dark Jedi is a Force-wielder who relies on the dark side of the Force without fully committing to the Sith. They may have been trained as Jedi in the order or possess abilities that they’ve tapped into and honed with anger, rather than the light. Dark Jedi were Force-sensitives who were devoted to the dark side of the Force but were not Sith nor members of the Inquisitorius. They were frequently former Jedi who chose to deny the light side of the Force or were Jedi-trained individuals who had abandoned their Order’s way to pursue a selfish and malicious agenda of their own design. The term "Dark Jedi" was originally meant to refer to a member of the Jedi Order who practices the dark side of the Force, whether or not they were a former Jedi. In summary, a Dark Jedi is a Force user who has turned to the dark side but has not fully committed to the Sith.
