I'd have to say homeless people. Listen to them, really listen to them, always keep in mind how damaged and afflicted they are, pretend to respect them, remove responsibility for their situation pinning the blame on someone else, give them new names and identities, introduce them to a few acquaintances but not close friends, family members, or love interests, do not allow them to clean or groom themselves, have different purities of heroin to soothe them when they are good or to hot shot them if you feel they may talk to the police. At a certain point any additional investment in food or money could turn out to be very shrewd.
