This is good thought op, I really appreciate your thought. We should practice our religion cause most of religion, we are following, advise us for good work, help people, work together, stand in One's side when they are in problem and live peacefully. But some people won't follow their religion at all. They are just in, that's all but do whatever they want. Besides there are many people who don't believe any religion. But the necessary thing is, we should be a good human being. Change yourself, world will be changed too
There are people who do not follow any religion, but that does not mean they are bad people. There are atheists who are good people and mind their own business, they won't even debate on religion and will respect other's faith.
On the other hand, there are an special kind of person who is more harmful than atheist, those who say to practice a religion, are considered to be religious leaders, and yet they only use that position in their church or community to get economical benefits for themselves.
It is typical the example of the fake pastor or priest who does not actually believe in his own faith, who rather keep his church as a business , they collect the tribute for the church to sustain a sinful life style, while his followers remain ignorant of that reality.
It is a deadly kind of hipocrisy in my opinion and unfortunately, I believe it is more common than we assume it is. It only takes a look at the cases of sexual abuse within the catholic church, if some priests are willing to sexually assault children then they are even more willing to misuse tribute money.
