God did not intend for humans to fall from grace. How does the intentions of God relate to a condition where His intentions were never meant? Capital punishment is the punishment for a crime God never intended to happen.
Your views are certainly in line with what 2267 teaches, however, it contains a prudential opinion of John Paul the Great (we get to call him venerable tomorrow, YIPPEE!!!

). Prudential opinions do not carry infallibility. The state makes the prudential decision.
The statement that recourse to the death penalty today should be “very rare, if not practically non-existent,” is a matter of prudential judgment (cf. Evangelium Vitae 56).

Here is the other article:
*What is the bottom line? Must Catholics adopt a particular view regarding the use (or non-use) or capital punishment? In short: no.
They are free to endorse, as a political policy, the complete abolition of capital punishment, and they are free to endorse the use of capital punishment, even beyond the very narrow limits given in the prudential judgment in section 2267. Contrary to what some people claim, there has been no revolution in Church teaching on the matter.
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.”
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.”
The Church does not mandate opposition to the death penalty, nor does she mandate support for it. This means that capital punishment cannot be listed as a “non-negotiable” moral issue, and that is why it is not mentioned in our “Voter’s Guide for Serious Catholics.”

*Please notice the bold. It seems that you are insulting those who have a different prudential opinion than you do.
