Zarvan bhai, it wasnt a major sin, but a minor khataa. How many do we make each day ? We dont know the situation of each individual there, like the kids. Also, the situation can also be interpreted as saving the spilled oil.
It was not 'Khata' but was a crime. Why are you justifying a crime which took lives of over 150 persons? Is it because you share the same tribe with those who caused this tragedy?
No sane person will justify playing with fire, when that fire couldn't only harm the player but other innocent persons too.
And sorry, do not fool yourself and others. They were NOT 'saving' the spilled oil. They did not return that oil to the owner, but they were taking it home for use. Please go learn ethics under a Maulvi Sahib or learn good manners from a Parsi or Convent school.
