Validity: The premises establish that intentional rights violations are the paradigmatic basis for punishment and attempts are nearly as clear, which logically supports the conclusion that as one moves further from this paradigm (more tenuous connection to rights violations, less culpable mental states), punishment becomes more controversial—and this reasoning is clearly present in the source passage.
Confidence: The text presents a clear argument moving from paradigmatic cases of justified punishment toward increasingly controversial cases based on proximity to rights violations and culpability of mental state.
