They used her position as the head of the child service department, in order to have control over the children and youths in the wizarding world. Of course, the children would be abused by their guardians, but then they could be led correctly, because Albus would step in for the clearly abused child as a benevolent grandfather and saviour and the said child as desperate it would be, would follow Albus’ lead and path. That was the same plan with Harry, but now everything would be for naught since he is with a new family.
