1. Have you ever heard the expression "correlation does not imply causation"? Maybe there is a grant available to study whether children of serial killers are more likely to create/view disturbing artwork if they've been witness to a parent's crime or not. Until such study I see no reason why or how this information is helpful.BBM:
The problem I see with your possible explanation for local young girls reading/drawing like VH did is that I will assume that none are the daughters of an accused serial killer who tortured his victims to death and caught with evidence that's a mine field.
Does VH not wonder where her interests came from considering she has an affinity for what her father was arrested for along with his blueprint that describes what's needed to carry out the images and reading material VH posted about?
2. We don't know what VH wonders regarding her choice of artwork and images, and frankly it's none of our business. She may well be trying to work through these questions as part of her trauma recovery (which now includes this extra layer of trauma and public humiliation).
