If you're familiar with who is leading this conspiracy theory then the weird posts here aren't all that surprising.
So yeah she might have made colleagues anxious because they knew she wouldn't gloss over their fuck-ups.
So you admit she had a history of making colleagues anxious? So you admit your previous staunch claim that Letby had no history of making colleagues anxious was not true?
Please provide proof for your allegation that the other nurses were making "fuck ups", because that's a very serious allegation to make without proof.
Nurse Lisa Walker testified in court that Letby had accosted her and told her off because she called for help when a baby started crashing. Walker did not "make a fuck up", she behaved exactly as she was supposed to.
Walker testified that Letby's behaviour stuck in her mind because it was so strange and abnormal. So that's one nurse who found her behaviour strange and uncomfortable.
There was another nurse who was assigned to a baby Letby had become obsessed with, and Letby got angry with her and demanded "four or five times" to be allowed to have the baby instead of the assigned nurse. To the point both the nurse and the parents found it weird and creepy because Letby was "really really angry" and persistent in wanting access to this particular baby.
So the claim that everyone loved her and thought she was an excellent nurse is just a flat out lie.
Difficulty making and maintaining relationships means ALL relationships.
Difficulty maintaining intimate relationships specifically is considered a potential red flag. The fact someone can make superficial casual friendships is meaningless. In fact, one of the markers of psychopathy is "superficial charm." Letby was clearly extremely manipulative and used things like her willingness to cover any shifts anyone needed covering to create this fake persona which occasionally slipped.
