So asking for your opinion means you will worry about my mental level? Seriously? 
Next time try not to bash others. I have not seen anyone defending acts like this happening in Pakistan. People try to bring reality that these kind of events can occur anywhere. But unfortunately you or others like you, see it as a defending the act. The problem is with you not with others who try to tell you otherwise.
So doesn’t this sad event make India the most dangeous country like you said earlier about Pakistan?
Man has not changed even in 21st century. The bad and good in man is timeless.
It is the technology and items of daily life which change over time. So your idea of people of 21st century are somehow better than people in the past is flawed.
