From a non-formal perspective...to me "sin" is a Christian term.

I believe more in Right and Wrong. I suppose my own individual conscience dictates which is which, though i believe it is Right to obey the law unless it directly hurts another person if i don't (for instance i would commit assault in self-defence or defence of a third party). It is Wrong to act in such a way that you hurt, inconvenience or upset another person unless it is unavoidable or for the greater good.

Morality is flexible though and most people will behave in different ways in the same situation depending on varying factors.
