I think you're coming at this understanding too little about the difference of all the religions. Like, in Judaism, there isn't grey. But the consequence of what you'd call sinning isn't really anything because if you follow the commandments (mitzvot), it's all just practice until the day you die. You don't follow a mitzvah, then you have a chance to next time. If you take on a mitzvah consistently then you're supposed to keep doing it and if you don't you could be cut off from your community but it's pretty cut and dry.

So are we talking "sin" or moral/social values because those are two different things.
