Licence to hit?

Dipu, a student of class four, died in hospital on July 5, after being hit by his teacher in the school. Some days later his teacher also killed a madrassah student. Do teachers have a special licence to hit and kill?

A teacher should be a student's best friend. They teach us to impart knowledge. If a student faces any kind of problems in class than it is the teacher who has the responsibility to solve those problems. Children will adopt behaviours of the adults. When parents or teachers use abusive words to children, they learn them and use these words in future. If a child does something wrong, teachers or parents must talk first, if it doesn't work then they must think about other alternatives, but not any violent action.

I strongly believe beating children will not help anyone, rather it will only create new problems.
