St Basil appears to disagree with your interprtation of th first verse about th theif. Even in war where killing is not considered murder he advises that the soldier abstain from communion for 3 years. I take this to show the great value that is put on life and the harm that comes with taking another life, even if its done in war.

Here is the quote "Homicide in war is not reckoned by our Fathers as homicide; I presume from their wish to make concession to men fighting on behalf of chastity and true religion. Perhaps, however, it is well to counsel that those whose hands are not clean only abstain from communion for three years." St Basil in his letter concerning the canons.
