On first glance, it seems difficult to relate the younger version of Aaron Campbell to the older one who committed this awful crime. I reread his appeal report recently and there’s aspects of his character described in there that I can see developing in the videos of him as a child.
If you watch the end of the video on the Jailbait Gaming channel, there’s a clip of him talking in his room. He’s articulate and comes across as likeable. He was assessed as having psychopathic traits such as a shallow, superficial charm which makes sense here as he wants subscribers. He’s probably good at manipulating others to like him.
In that clip he also makes an inappropriate sexual comment relating to his facial expression. It’s a bit weird, especially as he’s only about 12 at the time. Maybe the beginning of sexual thoughts that grew more depraved over the next few years? This is just IMO. I work with young people and just thought it was odd that he linked a silly facial expression to something sexual at a young age. It would cause safeguarding concerns (that they had seen/watched/experienced adult content at home) if I heard that from any of the children I work with.
