Personal Responsibility of the Narrator

In Melville's "Bartleby, the Scrivener" the narrator hires a man named Bartleby to work as a scrivener. The narrator observes that Bartleby is always the first at the office and the last to leave. After a while the narrator discovers that Bartleby has been living in his work station. When Bartleby refuses to work the narrator asks him to leave, and when Bartleby does not leave the narrator finds a new place to work. Even after he is gone though the narrator still remains curious of Bartleby and remains in touch with him after he has been taken to prison. I believe it is because the narrator feels some kind of personal responsibility for Bartleby since he knows of Bartleby's poverty. This personal responsibility kept the narrator from calling the police on Bartleby, and kept the narrator in touch with Bartleby. Ultimately it keeps Bartleby from fading from his memory after Bartleby has died.
