She refused to back down in her belief that what she did was right. Maybe not the lying about it to Antonin part, but everything else. She didn't want to be a mother. It hadn't been difficult at all for her to abandon Oliver after she almost killed his father. Sometimes she would think about him when she was on the run. Mostly it was to be glad and thankful that he wasn't there with her. She was poison. An innocent child like him shouldn't have to be exposed to a horrible mother like her. It was only as she'd gotten to really start to know her son without being under the influence of the potions that dulled her senses for so many years that she started to realize she liked him a lot. And when the memory charms were removed? She could finally see her son with clarity, see how much she'd missed out on by not being present for his childhood up until that point. But that didn't mean she was suddenly ready to have more children or that she regretted what she did to end her other pregnancies.
