It's probably using some twisted justification like saying that abortions cause harm to society as a whole, and that gives any member of society standing.
So raising a child in very suboptimal conditions is high chance of child turning criminal later on. Or parents dropping put of school to provide for the child. It can well be argued both ways.
More like "I'll be sent to hell if I don't save a soul". It's all selfishly motivated.
AFAIK that is the definition of a crime, and is enforced by the state accordingly.
