Why would a sociopath like Ted Bundy volunteer at a crisis clinic?

Answer 1

It was a requirement for Bundy's psychology studies in order to obtain his degree. The rumor was that when Bundy, when manning the phones alone, would turn the phone off so he didn't have to deal with people in crisis. When fellow volunteer Ann Rule was present Bundy was on his best behavior, councelling distressed people with the utmost sensitivity. As is true for most antisocial personalities, Bundy wore a mask of civility in order to live among normal humans without detection of his true self.
