The back story on her snatching the baby, was that the mother and father died while out in the field doing work. How she got the baby was she was traveling out of town, and heard the baby crying, and went to investigate. When she came upon the house she found the parents dead, the house ransacked and a crying baby nestled in blankets in a crib. She, with out thought, took the baby and ran, not seeing if anyone else was alive or if she had local family.
Does this fall under “evil intentions” or “motherly nurturing”?
Maybe a little of both, as she decided on Chaotic Good for her alignment.
Here is a twist I decided to add, her character was not aware of the older (but not enough to defend) brother who was hiding in the closet peering out.
So.. I could set this up for a whole brother on her tail, seeking out revenge, as maybe he thinks this character slaughtered his parents and stole his baby sister.
