If I become inactive with this massage, I died
I take it as toddler trying to take a shot at an adult using a rock, the shards are very much aware and fear that the Toddler will grow up one day and be pissed off at the adult shard, and that the rock will be replaced by an actual weapon, but as of right now it is just a toddler, especially when the adult keep throwing things at the toddler without killing them, and the things are random enough that they could accidentally throw something like accelerated growth serum.Examples of the humans having dimensional fuckery, and thus being able to figure out, if it's not already known, that travel between different Earths is theoretically possible.
Sure, they can eventually figure it out, but as of right now they are just a toddler and not a threat outside the most ridiculous of circumstances, the continued experimentations could accelerate this growth to a degree the toddler is growing right before your eyes, at which point the adults, in this case the shards, shoot him a few times, run, and nuke the planet the toddler was on from orbit.
To avoid it most shards don't want to deal with a toddler, they prefer to deal with a bunch of embryos, if one embryo start the accelerated growth than they kill it while leaving the others free of influence for continued experimentations, but by using an embryo they leave a lot of important things they can learn from a toddler and not from an embryo, let alone considering the possibilities two adults can open together even if they don't have test subject to experiment on.
When a cycle is finished the adult does the nuke everything from orbit thing, and all the adults around, the good and the bad die no matter how nifty toys they have.
QA in this case was always a little different from other shards, we know she had a little "defective" idea about what is dangerous and what was not, and we know she explicitly ignored much more safety regulations than other shards, which resulted in more crippling, after which she still managed to come up with new ways to fuck things up
Now I break the metaphor a little bit because the toddler was supposed to signify a society, not a person, but hear me out, Taylor in this case was spontaneously grown into an adult from one of the things that hit the children instantly, but left her disguised as one of the adults that do the experimentions, she can take QA to the side and build on what already there, she show her a toddler, QA know they are supposed to be in a close compound but seeing a toddler there, she fit it into her world view that some others came up more to her way of thinking and decided to start using toddlers, she would prefer small children, but this is good too.
This is what happening here, her misjudging Valkyries was bad in that she is supposed to play a host, not in that they are a threat physically to her true self, and to tell the truth, left alone she might not actually kill the toddler if it grows in front of her and get attached, this is just QA and this is who she is.
