Adoption and foster care, perfectly fine avenues in place for those who have an 'unwanted' child and do not wish to care for it. Not murdering the child in cold-blood as she did here.
Again, I hope your wife cheated on you and that you are sterile. You worthless sack of wifebeating shit.
Be that as it may, adoption generally is a long, drawn out process, and she was a frightened child. I feel that she did the right thing, given the situation.
