Evengli,

What other option do you want the parents and churches to teach the kids inorder to stop them from doing wrong?

For example If I teach my child that please donot steal anything from a shop or market because if the police sees you ,he will put you in jail or punish you.

do you think that the child will obey? What if the child after growing up finds out that the police itself takes bribes and is not sincere in its work. Will the child still be on the right path?

That is the difference between seculars and theists, theists guide there children according to the teachings of there religion and this is what makes difference between the bringing up of an atheist and a theist.
