It was indeed very sad to read of this incident. It is very rare something of such a nature takes place in any country across the world. Teachers are a beacon of light. They are the ones who lay the foundation for the future generations. They are a highly respected lot of people in all societies across the globe. It appears the accused did not receive any education let alone upbringing in a good, cultured family atmosphere.
I have seen many uneducated people giving great respect to educators even more than educated people do, as they realize the great value of education which life did not allow them an opportunity to get.
