She and baby daddy are their god. Created by them in their image.
You cannot blame parents for the sins of the child.
I have created children too. It's amazing.
The flaw in the story is that no matter how terrible your kids are, you do not condemn them to die. No matter how terribly evil they are.
This god, of love and forgiveness, condemns his most holy son to absolve you, and strangers, of their evil deeds and misgivings.
Real god would never ask you to kill anyone let alone ask you to kill his son. Why would god require the death of his son to forgive you? Are you not worthy of forgiveness otherwise? You're going to let someone die for you to be saved and then praise his name after the deed is done?
