Mentally Ill! Iknow This one person who does nothinng but lie and use people no matter who they hurt in the process and I've been told that person's Bipolar and has a Borderline Personality Disorder. You might be able to find some closure if you learn a little bit about these two disorders.
Also it is possible for a person of this type to be a sadist. Someone who causes pain in others for their own benifit. Or they are just a imoral person, fraud or fake, a manipulator. Its fair to say someone who intentionaly uses people is a sick person.
They also may be a sociopath. some sociologists believe that the world is run by sociopaths, who can fake emotion but have none, and therefore feel no guilt when they trample someone or manipulate people to gain power and prestige. There's no easy way to tell how common they are, but its estimated at around 1 to 4% of the population.
