Okay are you really sure it is not about religion? I beg you to let me rectify your error.
IT IS about religion, most of Pakistan is religious , and honor killing is something widely spread in Muslim countries to be more accurate.
Believe me ,it is about religion.
I personally know people who got killed and murdered for "dishonoring the family", so please,do not try to prove me wrong.
And one of them is my distant relative.
