So that's your choice. But if you are an atheist, there are no grounding principles that require you to live that way. You could decide that societal laws are not for such a one as you and scoff at them as you please. Or that rape is ok if you don't get caught, or robbery or murder for that matter.
Atheists have "no controlling legal authority".

Same goes for theists. All that is required for a theist to rape and torture and kill is for God to tell 'em to do so.
Would such a theist be nuts? Most likely. But then, so would an atheist who rapes and tortures and kills.
