Whatever the proper translation is, the proper meaning is not “kill.” No one understands that commandment to be a blanket prohibition against all killing, not even you.
Yes, I believe the general understanding of punishment that “we now have” is defective.
In 2266 we are told that the primary end of punishment is retribution. We are told that, however, in words that make the point anything but clear (“redress the disorder caused by the offense”). In 2267 the primary end is omitted in the discussion of how capital punishment is justified, giving rise to the misinterpretation that protection is the primary objective, and that capital punishment as retribution is no longer valid.
The defect I referred to specifially was in the perception of the nature of punishment. The phrasing of certain passages in the catechism has contributed to that confusion. I am far from alone in noting the difficulties in 2267.*Catholic teaching on capital punishment is in a state of dangerous ambiguity. The discussion of the death penalty in the Catechism of the Catholic Church is so difficult to interpret that conscientious members of the faithful scarcely know what their Church obliges them to believe. *(Dunnigan)
The most reasonable conclusion to draw from this discussion is that, once again, the Catechism is simply wrong from an historical point of view*. Traditional Catholic teaching did not contain the restriction enunciated by Pope John Paul II. *(Kevin Flannery, S.J.)
Yes, I clearly misread your comment. So to be absolutely clear: section 2267 has serious problems that need to be addressed, and it would help if the primary end of punishment identified in 2266 was clarified.
