Causes more harm than good these days. But people are entitled to their beliefs who are we to judge, if you don't believe in religion like me, you are only gonna have one opinion on it really (It's crap).
My belief about religion though is that it is just an old "tool" used to keep control over people, it gave them something to look forward to if they followed the commandments, and something to fear if they didn't. and because it was so powerful (in those times) it worked. Now people need more fact and arnt as stupid, so they will break the rules, and most dont really believe in it anyway.
More and more people are now turning away for religion. because (Excuse the pun/cliché) They have seen the light
