And to be frank, I see the appeal of choosing to believe in evolution or some other natural process of existence... Furthermore, he or she never feels responsible for there actions to a higher being. They can live life as they choose, with little to no consequences
I hasten to add that you can live life as you choose, with the exact same potential consequences I do. You choose to live life as a Christian presumably? I'm presuming if you thought it leads to immoral behaviour you wouldn't choose to live life as a Christian.
Incidentally - I believe I am accountable to a higher being: Everybody else. And regardless of how I choose to relate to that being, there's likely to be consequences when I act in a way that impacts on it.
