What's really wrong with giving up a kid for adoption? Maybe you realize that someone else could give the kid a better life. It certainly seems more humane than killing, but I guess it's all perspective. Too bad we can't ask the fetus.
I do think we should cut some of the red tape in adoption to ensure that kids get into a family quick rather than becoming stuck in an orphanage or, even worse, foster homes. I don't see why it's terrible. Someone doesn't feel they can raise a kid. Someone else wants to raise a child but can't have one or refuses to go through birthing. The kid wins by being raised by someone who we know really wants a shot at parenthood vs. someone who does not.
