The bottom line here is that some of the Jeremy Bamber supporters are actually victims being used by Bamber to enable him to achieve his narcisstic supply.
From my experience, some of the supporters will be knowingly mixing things up for their own amusement and for self serving purposes.
I posted this recently:
"Narcissists and Sociopaths compulsively strive to groom their victims for use and abuse. It is true — they are constantly striving to improve the quality of their diet as emotional vampires, compulsively inclined to play with their food.
Here is more about what to look for in interpersonal dynamics between human beings when one person is socially toxic, likely to use anyone who willingly allows them to unrepentantly abuse.
Narcissistic Supply sources are what Anti-Social predators seek. The more narcissistic the ASPD person, the more likely they are to strive to cultivate personality traits in their intended targets that please them solely as the dominant or ALPHA person in the relationship.
Notably, when a person with ASPD grooms a victim, very seldom do they take into consideration the best interests or needs of the manipulated person.
What matters most is having a willing subject for them to manipulate. Grooming, as a word commonly used to describe how sexual predators purposefully engage with child sexual abuse targets, is actually the same psychological manipulation technique employed by nearly all Cluster B individuals to trap or otherwise psychologically enchant their abuse targets.
