Should Afghanistan and Pakistan dis arm its population?

But the victim family has choice of refusing Diyat.

Yes but you know how things go. Killer get jailed, in couple of years victim family start to get over their family member death. Then they need to decide if to get huge amount of money ( by Pak standard) or continue with case.

Family get toghther and say, since killed isn't coming back anyway let's accept money and try to improve ecnomic situation of family.

How much money they would accept depend on how rich or poor both parties are.

Even with light arms, Pashtuns are murdering each other over trivial things. Jahiltob is the real issue

What happened to Jirga, is the reason people resort to violance is because of the breakdown of Jirga system and the lack of rule of law?

People can hurt each other with stones and kitchen knives as well but banning heavy weapons will at least reduce collateral damage.
Ofcourse no amount of banning is equal to education and getting rid of jahiltoob.
