There are plenty of names for the killing of another living creature. I do not view humanely strangling an unwanted child as murder.
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.
