To take away religion would be to take away hierarchy. The belief that one thing is better than another is a core human component that cant really be taken away without leaving you with a being without free will. People desire power and influence, they want their ideas to be the one that is accepted. Religion as whole is a construct to validate someones power over another. A way to establish a way of saying "im right" beyond he said she said. @Nymeria said it very well. You would have to literally strip pieces of humanity away, but it would create a near perfect species.
