I'd be extremely surprised from a psychological point of view if she ever wanted to even think of trying to go back to nursing after this, given that complete exoneration is highly unlikely anyway.
Drawing on personal experience again (sorry) the fear of ever being in a position where if something "went wrong" it would be assumed it was your fault is a powerful motivation to ensure you protect yourself at all costs. I still, 30 years down the line from my own experience, would never allow myself to be alone with a baby. My DC is an only, because I was warned not to have any more (not officially of course because technically they "can't" do that.) DC is in his 30s, and hasn't procreated yet. If he does, I will position myself as a relatively hands off GM and never be alone with his offspring until they are old enough - posdibly secondary school age. Not just to protect nyself, but to protect any imaginary childs parents, who might be penalised for not taking safeguarding concerns seriously enough. My DC knows the whole story, and trusts me. I trust myself. But I am on LA record as an abuser, and there is even the possibility that should he and his DP go that route, the system would flag up that he was the victim of abuse, and therefore also a potential risk.
People really fail to appreciate the cumulative effects of this sort of thing for both the accused and their families.
If Lucy Letby is realeased, and it's in time for her to perhaps form a relationship, have children, can you imagine the furore of "risk management"?
She'll never practise as a nurse again. She'll never have a "normal" life.
