“Cracked” would be on my list of one of the most unlikely websites to have an item relevant to this one, but here it is: a fascinating list of studies indicating that many external factors tip human beings toward ethical conduct, or away from it.

I gather from the list that looking at the CBS logo on a TV I can see through a broken window while being happily filthy standing in a grove of freakishly large lemon trees during a violent lightning storm will pretty much make me a saint.

You can read about the studies here.
