Do we know that the mother doesn't take any responsibility? I didn't see the Anderson Cooper video but I did read the article. She certainly isn't quoted as being sorry or taking responsibility for her part but that doesn't mean she doesn't have those feelings or thoughts. The person doing the interviewing and writing the article may have chosen to focus on making Dr. Reker the bad guy and having Kirk and his family be the victims of his horrible game. I am just playing Devil's Advocate here, but it is possible.
