all parents have responsibility for the welfare of their children and if they fail we have usually wonderful foster families to care for them, i feel sure williams bio family have great sadness and remorse every day for allegedly not getting their lives together for william and his sister and getting them removed, maybe they felt a small hope that the children would be returned when their lives improved, and they were trying for their return when william disappeared, the amazing carers who choose to care for these children and promise to love and keep them safe are all aware these children in care have biological families who may one day choose to be in their childs lives again, these carers are paid to keep the children safe so id expect if you lose someone elses child you would show remorse, maybe the fcs have, privately?
