Also if u look at her depiction and progression of her character its in line with an abuse victim and person with a mental disorder which would make her unfit for thst responsiblity.
And if you want to paint her as trash then in the same breath we should also paint her brother and nanny who were her emotional abusers and were the ultimate cause of all this as irredemable and while we are at it paint her husband who knew the child was being abused but chose to do nothing not even separate the child from her as trash since he effectively encouraged the abuse by willfully letting it go on umder his roof.
