I was referring to her brothers
They're not wrong for their actions though. Good people don't bargain with the lives of the innocent, and if their sister won't see reason they are just in their action to step in. You can try to reason with the hag but no, she wants the baby and the mother isn't much more reasonable. So violence it is, and certainly justified. You sound like you are interested more in a lawful evil role with more of a corruptive role rather than stabbing. More of a lawyer of the devils type.
My entire point was that Mayrina's brothers are the only "good" people that we meet. xd
To be fair to Mayrina, she thought that Ethel was actually going to raise her child as a wizard, an education she feels she could not provide the baby alone.
