While experts found Bundy's precise diagnosis elusive, the majority of evidence pointed away from bipolar disorder or other psychoses, and toward antisocial personality disorder (ASPD). Bundy displayed many personality traits typically found in ASPD patients (who are often identified as "sociopaths" or "psychopaths"), such as outward charm and charisma with little true personality or genuine insight beneath the facade; the ability to distinguish right from wrong, but with minimal effect on behavior; and an absence of guilt or remorse. "Guilt doesn't solve anything, really", Bundy said, in 1981. "It hurts you ... I guess I am in the enviable position of not having to deal with guilt." There was also evidence of narcissism, poor judgment, and manipulative behavior. "Sociopaths", prosecutor George Dekle wrote, "are egotistical manipulators who think they can con anybody." "Sometimes he manipulates even me", admitted one Psychiatrist. In the end, Lewis agreed with the majority: "I always tell my graduate students that if they can find me a real, true psychopath, I'll buy them dinner", she told Nelson. "I never thought they existed ... but I think Ted may have been one, a true psychopath, without any remorse or empathy at all." Narcissistic personality disorder (NPD) has been proposed as an alternative diagnosis in at least one subsequent retrospective analysis.
