The term for that is "retroactive abortion"
I heard a comedian joke about that idea several years ago. He believed that parents should have the option for retroactive abortion at least through the child's 18th birthday. Anyone who has raised teenagers can understand that viewpoint.
Having survived raising two stepsons through their teen years, there were times they were lucky no such law exists. Fortunately, most of them grow up to be good adults. My wife and I look at our youngest (now 28) and can hardly recognize him. On the other hand, our oldest (now 30) still acts like a teenager in all of the bad ways. Sad. Really sad.
