Yea I mean this really emphasizes the fact that religion was really brought about as mind and behavioral control of the masses. It offers a reward for those whom are good citizens and obey brotherly laws. It is a good thing in that I scares the non-thought provocting inside the box people into good behavior and practices. The problem most people have with atheism, and probably the reason 50% of the world or more isn't atheist is that it doesn't offer these 'perks' the other religions offer, like heaven, nirvana whatever it may be. At this point most of them see the evidence mounting against and simply cling to there religion as a 'safety net' which is deffinately the worse position to be in. Your neither a Christian or an Atheist or anything else and your wasting your time in church etc.

That was just my little blurb, as to your question I don't think that religion is the only reason for mutual and non-mutaul positive human interaction and if it is your only motivation to be kind to your fellow man that is sad.
