Who is to blame?

I was in a microbus going to Satdobato from Sanepa. One of my friends was with me. We were going to our college. Near Nakkhudobato a small boy got into the vehicle and sat next to my friend. He was wearing a large coat to hide himself from the chill of Kathmandu's winter. I was thinking and telling to myself how unfortunate the child was. I was wondering if he had the money to pay for the ride. It was not even one kilometer when he got up from his seat and shouted "yaha rokh" in a very mean and strong tone. The conductor asked him for money and to our shock he pointed a knife at him and yelled "paisa magchas? dinna ja". The conductor caught him in his neck and threw him outside like a garbage bag. The boy was still shouting and showing the knife at him. One of the fellow passengers told the conductor to cool down and never to allow any "khatey" to get inside the vehicle. Everyone nodded to show their agreement. The conductor in rage continued “yestai ta hunchan ni pachi ka gunda”.
