Does the religious myth benefit modern society or not?

[DanneSandin]

I don't believe religion is beneficial any longer. It played an important part in society and human psychology in the past, but nowadays it does more harm than good. People really don't need a god to be happy, that's a misconception.

Also I think that religious people are more me-centric because it's all about 'my religion', 'I'm going to heaven, you're not'. Isn't that kinda egocentric?  Thinking that you know the answer to eternal happiness and a happy life hereafter, while the rest of us is gonna burn for eternity. ..
