The wisest way to lead our child to a positive life is to teach religion to them...
I disagree. It's wise to teach children
about religions, not to force them into a certain religion.
With the increasingly free and easy access in this era, it is very natural for us as parents to worry about the future of our children. people who are involved with prostitution and drugs certainly do not have a strong belief in religion, they only care about lust so that has led them since they were young to know more about religion, according to your religion.
What about drug cartels from Central and South America? They build churches, have altars in their houses, wear jewelry with religious symbols and often pray.
Taliban terrorists are usually very religious as well.
It's important that children learn to be good people, know ethics. Telling them that they can always wipe away some sins through confession will not teach them responsibility.
Teaching a child the difference between good and evil and the consequences that follows afterwards is one other way of best teaching a child how to grow. Giving them the power of choice while still very young and having them face the consequences squarely will in a very large sense curtail and make them understand certain ethics and morals of society.
Religion alone haven't really helped as expected thus this far due to how it has been infiltrated by deviant men in society.
