All entity-related categories are subcategories of Beings since Category:Entities was deleted. Beings is also not very clearly defined in my opinion. It seems that if the entity is "mysterious" enough to ellude a specific label, it is put in Beings. That includes entities that may or may not be human, and sometimes even those that clearly are. The fact that it frequently overlaps with other entity-related categories doesn't help, either.

Perhaps creating an entities sub-section of the genre listing would be better than putting them all under beings, since making it a category didn't work (people were constantly adding it to pages when it was supposed to only serve as a directory for entity-related categories).

In any case, I would have agree that serial killers are not really 'beings' in the sense that they are usually unambiguously human. On the other hand, trying to find a way to organize these categories is giving me a migraine, so I'm doing it this way for the time being.
