The ethical tenet is that it isn't right (and isn't my place) to withhold the consequences of someone's actions from them.
What if my child slaps a dog or pulls on its tail? What if my brother gets caught stealing money, but the punishment is exceptional and I can mitigate it?
Consequences are how we learn from our actions, and it does people a disservice to try to shield them from those. However, given certain individualized circumstances, something might be unethical to do, but moral to do. Of course I'm going to try to help my brother, and it would be wrong not to do so. Of course I'm going to try to save my child from a bite, and it would be wrong not to do so.
Ethics tend to be absolute, whereas morals tend to be situational, at least in the manner I was using the terms.
