Yes, great point. The actions need to be connected to the consequences. I realized at one point while my children were growing up that they equated the word "consequences" as synonomous with "punishment". That had to do with school and establishment of classroom rules, etc. I had to sit them down and explain because I wanted them to understand that the true meaning of that word was "results". Consequences are not always negative or punishing. They are simply the results of your actions, be they good or be they bad.
I think our stabber is past all that now, though. I'm skeptical that he will ever see his actions as wrong.
