The harsh reality of that era was that countless “ladies of the night” were subjected to violent attacks, which in some cases resulted in their deaths. According to criminal psychology we learn that serial killers tend to have a very good grasp of other people’s emotions and are quick to pick up on any vulnerability or weakness in order to convince them into doing things they normally wouldn’t. That’s why it is believed that Jack the Ripper was probably a kind charmer while approaching his victims.
