The Coach was not Bad. He did everythig for the street child who had been slod by his mother to another person. What they say torture, was perhaps the reflections of a high ambition by Biranchi that he tried to realize through the kid.
When the kid attained some fame, it was his mother's crooked mind that wanted him to be freed from Biranchi. Now his mother has enough to eat (thanks to Biranchi for bringing this kid out of darkness, and the govt followed) so didnt care to become ungrateful. The kid was also brainwashed and repeated what his mother wanted him to say.
I dont feel the kid's story has got anything to do with Biranchi's killing. Both topics may not be related. I am sure there is some other deeper conspiracy behind it.
