It's unusual for someone who kills in a manner categorized as mass murder—more than three people in a single location—to go on to commit that same crime again. We may think of the Manson Family, who in 1969 killed five people at the Sharon Tate/Roman Polanski residence, and the next night killed the LaBianca couple, but that was in response to a vision and not the act of a single perpetrator. However, there have been a few notable cases.

As for the Ratcliffe murders, the motive remained a mystery and a source of conversation for crime buffs in the decades to come. Colin Wilson indicated that Williams was syphilitic and harbored a grudge against humanity. Thus, he was acting out against people in general and would have continued to do so. The fact that the murders stopped after his apprehension and death, he added, was an additional indictment against him.
However, James and Critchley believes that the proceedings were performed too quickly as a way to close the case and appease the frightened citizens. An early witness report insisted that the two men seen on the road that night outside the Kings Arms tavern had spoken and one had called out what sounded like a name—Mahoney or Hughey. William's name did not sound like that, but once he was in custody, that piece of the puzzle was soon forgotten. These authors do admit that Williams had misrepresented himself on occasion and was perhaps going by an alias, but following leads about two men walking up the street together (who were not proven to have had anything to do with the murders) dismissed the facts about the open tavern window and the footprint in the mud outside. They believe that it was possible someone else had perpetrated the assaults, making Williams merely a tragic and unfortunate pawn.
