I understand what you're saying. If someone punched me in the face i wouldn't judge them as being bad, but i would consider their action being bad. I'd wonder why they would do such a thing and try get to the bottom of it and explain that acting out that way is harmful. Who likes getting punched in the face? hehe Not many people.
Labeling actions doesn't cut me off at all from understanding. If no one knew punching others in the face wasn't a good thing then we'd all have black eyes. In order for clarity you don't need to just understand why the situation is as is, but also what the right thing to do is, how to act in a way that won't cause that sort of harm.
