No one knows that, and it's a disservice to humanity to push this narrative.
She committed crimes, and is being rightfully punished. That doesn't mean as a human she looses the right to have a family. I imagine facing a very long stretch in prison that will take you past the point where it's possible to start a family motivates you to consider starting one.
But that's not to say it was a "good" or moral choice for her to make - I feel for any child who parents are incarcerated.
As much as people like to see criminals as 2d villains, they are humans with fundamental human drives.
