You do not want to understand that there is nothing in Islam says that raped women must be killed .
And you do not want to understand that Afghanistan is not ruled by Islamic sharee'ah.
===========================================
The sharee'eh rule in rape case is:
the man must be killed
No any penalty for Women
If pregnancy occurs the child carries the name of his father and the all rights in society are guaranteed
