These days, we come across good
people who care about themselves so much
they seem to care about nobody else. Unfortunately, that provides a breeding ground for bad people. These are bad people who mislead, deceive and in other ways exploit many innocent people whose only weakness is in being credulous and gullible.

And it does not get any better when established history and culture of a civilization gets distorted by those seeking only to spread their religious beliefs at any cost.
Maybe it's time to remind ourselves of an insightful observation from a learned man. He said:
The world is a dangerous place not because of people who do evil, but because of good people who look on and do nothing about it. -- Albert Einstein

Note :  As we are living in this 21 century with internet communication, one could spread a message quite easily via the net, but not to forget, the root course of a lots of the problems are the end result of  the teaching from our parents, our teachers, our religion, our society and our government, which has a lots of impact on the behavior of mankind......

To get kick start solving the problem, start teaching your children with manners and respect to parents, the elders, neighbor and with good civil manner.
