@alternate bro,
I agree morality is a broad term. Can you be good without religion?. Yes. But what was the origin of moral learned behaviour?. It is religion. You might recall your hindu upbringing and how that has shaped your morality to a certain extent. Also the other question remains, is being good enough?. Or do we have to rise above just being mere oridnary humans?. Donating, giving seat to elderly,adopting kids, blood donation, etc all appeal to a higher sense of morality . I dont see how evolution satisfies this search for morality. Great people like mother teresa, florence nightingale have been produced by religion.

Also how could an unconscious origin give rise to good and bad morality?. How could unconsciousness give rise to consciousness?. These are also valid questions that need to be answered. How does a purposeless universe account for morality?. 

I agree there are lots of demerits in religion. I am an agnostic theist myself. However, i dont see how demerits of religion justifies Atheism. The main question of life still remains unanswered. Religion still serves some purpose to life. The concept of God remains valid. 

You are also talking about ulterior motive for doing good. You are saying why not do good for the good that it is. Doing good for the fact it is good is a religious teaching. Not only that some teachings ask people to rise up and become more than just ordinary humans. How then do we make a better society if we do not rise up beyond the ordinary?
