I still find this an odd way to look at things. If Julie is all that, then Jeremy is guilty and you (and a few others) are vilifying her more than him. I can understand someone defending Bamber because they think he's innocent, but not the above approach.

"Hello,
Welcome to Knowing the Narcissist.
I am H G Tudor. I am a narcissistic sociopath (some state psychopath – this remains a matter of debate by the profession concerning the current application of sociopath or psychopath).
By my terminology I am a Greater Elite Narcissist. You will learn here what that means along with all about the other types of narcissists and empaths too.
I convey this is an effective manner based on my perspective. I know what I am and I know the best way to communicate this to you. I am a very effective communicator.
I write extensively about what this means and what I am. I have practised this dark art for many years, I have honed and crafted my abilities. I am aware of what I am and I am engaged in understanding why I am this way and why I act as I do. I am sharing these ongoing revelations.
I know my kind in considerable detail. I have several family members who are narcissists and have engaged with numerous in my life. I know the way my kind think, why we act as we do, say what we say and so much more. I understand why we target our victims and how we go about it. I comprehend why our victims think and act as they do. I have had many, watched many and listened to many. This allows me to build a formidable body of knowledge about not only my kind, but the people we engage with.
