The babies that are still being used need to be given proper burials - not still be in a labratory environment because "they were already dead".
How do you bury a stem cell? It’s a cell. Now you are being unreasonable. Their temporal flesh, whatever existed, has been destroyed. Ain’t getting it back. The babies are with God. The lab didn’t destroy that. That’s their real essence. What was done to their bodies is done and unless you want to bury a bunch of slides and suspended liquid then you’re just being unreasonable at that point.
