The level of glorification of birth parents, despite whatever damage they inflict on their children, is appalling.
Some parents will put in the effort given support, and will do what they can to parent well. Sometimes they can, if they can't but have done their best it is heartbreaking for everyone involved. Others are too wrapped up in their own needs and fantasies.
As an adoptive parent I know that the damage done to small children has a life long impact.
Both DDs are doing incredibly well, and building good lives as young adults. They are thoughtful, caring and responsible, and have a wonderful sense of humour. They understand and have compassion for their birth mother (less for birth fathers who didn't even try to parent). But they continue to struggle with their mental health, because of their early years.
Being pregnant and giving birth is just the start. If someone can't put their own wants aside enough to see their baby's needs then the baby should be protected. Babies are not inanimate possessions.
