Page "Bender (Futurama)" Paragraph 35

Despite these human characteristics, Bender has no detectable soul, as seen in " Obsoletely Fabulous " when he passes through a ' soul detector ' without an alarm sounding.

But in " Ghost in the Machines ", due to his suicide, Bender is turned to a ghost who can't interact with people and can possesses machines: he used this ability in order to " scare Fry to death " when he makes a deal with Robot Devil to get a new body.

Though never addressed, an explanation to this seeming contradiction can be found on the fact that, as noticed by the Robot Devil himself, Bender's spirit existes on a universal wireless that allowed him to travel in the physical world while trapped in a Limbo-like loop.

The fact that Bender's ghost is an incorporeal program rather than a soul is further supported by the fact that the " spirits " on " The Honking ", where actually mere holograms of an old computer folder.
