Gone are the values
Is it because how they are educated in the school, is it how they are raised by their parents, is it because the society where they live - I can't figure out. But it appears to me that it did not alarm the bell, except the mothers of the victims.
Raising children is a very difficult job, especially when the human value and integrity matters. Society is not always on your side.
Inducing polity into the society is a big job and can be done only when everyone has basic awareness. And that should come from education. Governance can impose the norms; society should also eagerly exercise the fundamentals of the expectations.
I guess, we are failing at every step.
Our teenagers finding no exemplary guidance, no leading character to emulate, are rather twisted within a culture of despair only. Blaming others is a fashion but not the remedy.
