Can you explain what you mean, you don't think that she didn't intended to kill the babies ?
She knew full well that doing those things would cause death,
not only because of her medical training but because she watched multiple babies die after tampering with them and she still continued to do it
which leads me to believe that causing death was her main goal
she even went back and killed/ tried to kill some of the babies that survived
She seemed to enjoy the whole process of the baby dying,
she enjoyed everyone being heartbroken by the death,
she enjoyed the parents pain, and all the tragedy
she liked putting the memory boxes together and pretending to comfort the parents
she liked getting sympathy from her colleagues
multiple people described her smiling and being giddy during these moments , where most people were sad and exhausted by it, Lucy was cheery and energised .
I haven't seen anyone else mention this but my opinion is that she was trying to recreate how doctors and nurses are portrayed on tv shows,
In medical tv dramas, every minute there is an emergency, there is lots of drama
like house, greys anatomy
even her supposed affair with the married doctor ties into this theory
maybe she never had an accurate idea of what working in a hospital was actually like and so she found herself disappointed
I think she actually made this clear a few times, that she wanted to be where the action was, and so she created it
Whatever her motivation was
she was willing to sacrifice the lives of these infants for it
she didn't care if they died, she didn't care that she was causing them excruciating pain, I think she saw the babies as nothing more than props
I remember hearing different accounts, some from the mothers and nurses
describing the distinct squeal/cry that the babies made when Lucy was attacking them, and they would run into the room and see that evil witch standing over them pretending to help them
which proves that she was sadistic, she stood there and intentionally caused them pain , she is an actual monster
she wasn't just mechanically injecting air and insulin into them,
there where times she caused traumatic injuries, like child N,
she forcefully thrusted a nasogastric tube down his throat
