Reading another thread has made me keep thinking this question. I don't understand how anyone can be totally one way.
For me I think it is up to each person and I wouldn't judge anyones decision.
I personally think that whether to keep a child is complex. It changes your life forever when you have children! I don't see how it is beneficial to mother or child if their lives will be miserable.
You only get ONE LIFE and need to make the most of it.
