the “I am evil” could easily be taken as someone speaking figuratively or from the mindset of someone placing themselves in the shoes of someone who actually had done it. Depends how much weight you add to it.
im confident the unit more or less as a whole were in utter disbelief when they moved her to clerical. The pers coms give absolutely no indication that she was indeed suspected by her fellow nurses or indeed senior staff, they all seem mostly tight. Including some docs. I can imagine them trying to reassure her whilst being on clerical, giving her some fuel to stay and see it through. i couldn’t really say what happened after, with it being downgraded to a L1 though. Probably zero deaths at all. Remember none of the nurses testimony has actually been damning of her at all, they didn’t see anythin or even reported concerns or anything at all. I might guess that they thought the same of her but will without a doubt be looking to the Verdict.
