I still can't stand her
That's the point of the meme,lol
But also they specifically made her character unlikable. You were supposed to find her irritating in comparison to Walter, who is an objectively worse person. I think that was almost the entire point of her, to make you side with an objectively bad person over the other slightly less objectively bad person.
This is exactly where my mind went. I can't imagine she was just leaving school and decided becoming a nurse would be the best route to killing babies. Or maybe I just don't want to.
A common thing with killers is that they enjoy the rush, I wonder if that's something that developed while she was working, as in she felt that during her legitimate duties and had to push it further and on her timetable.
A monster, regardless.
