Under the sky...

'The measure of a man's real character is what he would do if he knew he would never be found out.'

I read this yesterday in a little lame joke/quote book I have.
What would you actually do if you knew you would never be found out?
What would would you do if you knew you could never be found out by God?

As impossible as that is, it's a scary thought, and I really have no idea what I would do, but I wonder what I would be capable of. I'm generally a follow-the-rules person as a principle, but would my morals stand by me if I knew no one would ever find out what I'd done? Would I still carry the guilt, the shame, if I'd done something terrible?

I'd like to think that I wouldn't do something terrible, but the truth is, I really don't know.
