Mugford had no option but to confess. It was either that or be charged along with Bamber. She was intelligent enough to know where her future lay. After all, she did admit to knowing of Bamber's threats towards his family yet she did nothing choosing instead to feather her own nest. Little wonder she is now vilified imo.
I am of the opinion the CPS recognised JM as a victim of psychopathic abuse at the hands of Jeremy Bamber
"At some point, however, the evidence of a highly disturbed personality shows through, especially once the psychopath is no longer invested in a given victim and thus no longer makes a significant effort to keep his mask on. Then total denial is no longer possible. The floodgates of reality suddenly burst open and a whole slew of inconsistencies, downright lies, manipulations, criticism and emotional abuse flows through to the surface of our consciousness.
However, even then it’s difficult to absorb such painful information all at once. Our heart still yearns for what we have been persuaded, during the luring phase, was our one true love. Our minds are still filled with memories of the so-called good times with the psychopath. Yet, the truth about the infidelities, the constant deception, the manipulation and the backstabbing can no longer be denied. We can’t undo everything we learned about the psychopath; we cannot return to the point of original innocence, of total blindness. The result is a contradictory experience: a kind of internal battle between clinging to denial and accepting the truth.
Cognitive dissonance is a painful incredulity marked by this inner contradiction in the victim’s attitude towards the victimizer. In 1984, perhaps the best novel about brainwashing that occurs in totalitarian regimes, George Orwell coined his own term for this inner contradiction: he called it doublethink. Doublethink is not logical, but it is a common defense mechanism for coping with deception, domination and abuse. Victims engage in doublethink, or cognitive dissonance, in a partly subconscious attempt to reconcile the contradictory claims and behavior of the disordered individuals who have taken over their lives.
The denial itself can take several forms. It can manifest itself as the continuing idealization of the psychopath during the luring phase of the relationship or it can be shifting the blame for what went wrong in the relationship from him, the culprit, to ourselves, or to other victims. In fact, the easiest solution is to blame neither oneself nor the psychopath, but other victims. How often have you encountered the phenomenon where people who have partners who cheat on them lash out at the other women (or men) instead of holding their partners accountable for their actions? It’s far easier to blame someone you’re not emotionally invested in than someone you love, particularly if you still cling to that person or relationship.
