I've been reading back over the last few pages of this thread. I've been really impressed by the insightful comments, particularly #563 #576 and #581 from stmarysmead, #584 from Frizby, #634 from francesca and many more from kittythehare.
One more tuppenceworth.
From KMs book, I think it's fairly obvious that MM was(is) bipolar. It's not a condition that goes away, and reading about the behaviours, I think it's pretty clear that she lied when she said it was a mis-diagnosis. In my experience (by proxy) it's often the case that the 'higher' the manic episode (high energy, racing thoughts, grandiosity, risky behaviour) the 'lower' the subsequent depression (feelings of sadness, loneliness, worthlessness, uselessness, regret for behaviour in the heat of mania.
More than any prison bars, I honestly believe that the punishment that awaits MM when she looks in her mirror will be her own mind rebelling...
Now TM (and possibly SM/ME?), their grandiosity was different IMO, more of a (narcisstic?) underlying personality trait. One that the jury (God bless'em!) recognised implicitly. I honestly believe that in that echo-chamber inside his own head, when he discovered what had happened on 2nd August 2015, he went into survival mode. By survival, I mean survival of his (and by association his family's) status, standing, reputation. Other considerations were simply unimportant trivia - JC's reputation, J&S, MrF, all just details to be moved about like pawns in his over overweening master-plan and facilitated by his legal team. This is what he does after all - "spy against spy stuff". But narcissism generally masks a fragile self-esteem.
So I wonder, what awaits him when he looks in the mirror? In a month. In a year. In ten or fifteen years?
Maybe, out of the corner of his eye, the Truth will come creeping...
All IMO
