I have to admit, reading the discussion between you and Ender has prompted me to do some reading of my own. Karl Keating wrote an e-letter back in 2004 on this very point:
catholic.com/newsletters/kke_040302.asp
From that article:
Hasn’t the “Catechism of the Catholic Church” imposed a new regime to which all Catholics must subscribe? Hasn’t the Church fine-tuned her teachings in recent years so that Catholics now are obliged to oppose the imposition of capital punishment except is cases so rare that they may be considered to be almost non-existent?
This would certainly seem to be your position. Interestingly enough, there was some analysis, done by an expert, on this very point. Karl outlines some key points from that article in his e-letter. You may have to register to gain access to the actual article from Fr. Dunnigan, but here’s a link:

From Karl’s article:
In short, there is an ambiguity in the “Catechism.” Other punishments are looked at not just in terms of legitimate defense but under all three purposes of punishment in general. The death penalty, for some unexplained reason, is looked at only in terms of one of the three purposes, protection of innocent parties.
Which is a great point. Why is the death penalty excepted? Cardinal Dulles thinks the Catechism is not expressing what an out of context plain reading of 2267 lead many to think. Rather, it must be understood in the context of traditional Church teaching and the reasons for the text. As Karl wrote (emphasis mine):
How are we to understand this? Avery Cardinal Dulles has noted (in a letter to the “National Catholic Register”) that a denial of retribution as a legitimate purpose of capital punishment would be contrary to the traditional teaching of the Church, but this is not, he thinks, what the magisterium is doing in the “Catechism.”
Code:
**Dulles believes that section 2267 and "Evangelium Vitae" are not Church teaching, in the proper meaning of the term, but reflect the "prudential judgment" of John Paul II.**And Karl's conclusion is most telling:
You can be a good Catholic and think that the death penalty should be done away with entirely, and you can be a good Catholic and think that it should be applied more often than “rarely.”
Code:
You are not bound in conscience to adopt one position over the other. You are free to make your own prudential determination--but you are not free to say that someone whose prudential determination differs from yours is therefore a "bad Catholic."
I hope this is a lesson we can call understand and learn from.
