A woman in Oman tried to kill herself after killing her two children. After making a call to the police that she killed them, she tried to follow them to death but was stopped by the police. While her children were strangled, it's not clear on how she planned to kill herself.
Her failure means that not only would she not be able to be with her children (assuming one believes in the afterlife and that they would go to the same place), but she would also have to live with the fact that she killed her own children while she herself survived. That must be one of the most terrible positions a mother could be in. Not that she was justified in killing her children in the first place: while her life is her own, she had no right to take away all possible futures from her children.
