Murder of a human being is never justified, it is extremly condemnable, but reasons of this murder are to be traced in the social values and family background of Qandeel Baloch (although it is not an excuse or justification but one cannot change the social setup overnight).
If you listen the above clip the critics of Haroon ur Rasheed are actually agreed with him by saying that statement is true if it is about all the participants of the video, here I'll say again that don't forget the family background and social values of the singer which are quite different from Qandeel Baloch, if both girl and boy would have been from the same social background then it would not end in honour killing.
