Sociopaths

[FooFighter]

Heh, I know what you are talking about. While most of my characters aren't exactly sociopaths (Mireille might be slightly sociopathic, but she has enough opportunities to kill people and she usually restricts herself to known enemies of the Revolution, and my other char who has been RPed as someone with severe social problems...well, let's say the problem has been solved), I usually do something like adding a character who enjoys communicating with other people to the crew of my larger ships, like Itakura Ayane - the communications officer of the RV Victoria - who is quite chatty, because she knows that the ship will soon depart into Edge Worlds (or even beyond) and likes to have some social contacts before being alone with the rest of the crew again.

In your case, Sophie could have an assistant who is actively probing people around her to discover people who could be good victims to her mad schemes or something like that. The assistant could, for example, try to lure people who seem to be harmless enough to dock with your ship, under the guise of needing some help repairing that darn gravity pads near the engine rooms which work as if they were bought from some random Junker passing by. I guess Sophie would need a fresh supply of victims from time to time after all, and there might be people who would be more "fun" than just stupid slaves...
