I would definitely say environment where you were raised is a huge factor but it's more individual mindset which is why atheism is an INDIVIDUAL decision NOT a methodology for a group to follow.
You need to inherit the moral framework from somewhere, after which it's possible for certain individuals to retain it without needing the reinforcement of it via religion. The filthy unwashed masses however, largely require regular maintenance in the form of church in order to retain their moral framework.
