Simple is nice

I once read a book called The Kite Runner and, if my memory serves me well, one passage had some words of wisdom from a father to his son. It's been a while since I read it so I'll have to paraphrase. It went something like this...
Son, I will ask just one thing of you and that is that you do not steel. When his son asked how such a simple philosophy can encompass all that you need to live a good life his father replied: My son, if you kill someone, you have stolen his life. If you are unfaithful to your wife, you have stolen her belief in you as a husband. If you lie to someone, you have stolen their trust.
There was more to it than that, and put better than I have here, but you can see the idea.
As an atheist/agnostic myself, my own philosophy is simply to treat people as I would wish to be treated. If I was a traffic cop, no matter how much money they offered to pay me, I honestly couldn't point a speed gun at someone going just over the limit whom I know to be driving safely - I would be a hypocrite! Sadly, there are plenty out there who will, and do.
However, I would happily be a traffic cop ready and willing to pull over someone who's driving dangerously or whom I suspect is driving under the influence of drink or drugs.
In this dog-eat-dog world I guess it makes me a weaker person but then I'd rather be hated for who I am than loved for who I'm not.
Sorry - got a bit deep there.
