From a passive observers point, of view, it'd be best if she's found not guilty i think. If it was my child and i've got the choice to believe 'my kid was murdered by a psycho nurse' or 'my kid died naturally' I think I'd prefer naturally, and I'm not sure why, as both are too horrible to contemplate.
It's ridiculous though, when these serial killers get a retrial for one victim, when they've been already been convicted of 7 murders, as if they have any intregrity left?, and as if, in Letby's case it's gonna be a mitigating factor or something.. like how about the babies she could've killed but didnt. Close the book, lock the door and throw away the key
