If she was gonna live for the orphanage and only the orphanage and not being able to take care of her own child, mb she shouldn't have gotten a child in the first place. Orphans do deserve. That I do not deny at all. But your own child, who had a mother alive, had to feel that he was an orphan himself as his mother was fixated only on the orphan kids. Basically by doing sth good, she ended up not doing sth important.
