“Commensurate” does not mean kill.
In the case of premeditated murder and Church teachings, a commensurate sanction does mean execution, precisely.
Look at the Catechism:
The biblical foundation for the death penalty is found in Genesis 9:5-6 and is based, specifically, upon “shedding blood”.
2260: “For your lifeblood I will surely require a reckoning… Whoever sheds the blood of man, by man shall his blood be shed; for God made man in his own image.” “This teaching remains necessary for all time.”
2261 Scripture specifies the prohibition contained in the fifth commandment: “Do not slay the innocent and the righteous.” The deliberate murder of an innocent person is gravely contrary to the dignity of the human being, to the golden rule, and to the holiness of the Creator. the law forbidding it is universally valid: it obliges each and everyone, always and everywhere.
“An ‘innocent’ person.”
2258 “Human life is sacred because from its beginning it involves the creative action of God and it remains for ever in a special relationship with the Creator, who is its sole end. God alone is the Lord of life from its beginning until its end: no one can under any circumstance claim for himself the right directly to destroy an innocent human being.”
“An ‘innocent’ human being”
Always and everywhere there is the prescribed sanction of "For your lifeblood I will surely require a reckoning… “Whoever sheds the blood of man, by man shall his blood be shed.”, which, is confirmed in the Council of Kent, that execution represents paramount obedience to that commandment.
“Paramount obedience”
Saint (& Pope) Pius V, “The just use of (executions), far from involving the crime of murder, is an act of paramount obedience to this (Fifth) Commandment which prohibits murder.” “The Roman Catechism of the Council of Trent” (1566).
- Pope Pius XII: “When it is a question of the execution of a man condemned to death it is then reserved to the public power to deprive the condemned of the benefit of life, in expiation of his fault, when already, by his fault, he has dispossessed himself of the right to live.” 9/14/52
- Pope Innocent I" "It must be remembered that power was granted by God [to the magistrates], and to avenge crime by the sword was permitted. He who carries out this vengeance is God’s minister (Romans 13:1-4). Why should we condemn a practice that all hold to be permitted by God? We uphold, therefore, what has been observed until now, in order not to alter the discipline and so that we may not appear to act contrary to God’s authority. Innocent 1, Epist. 6, C. 3. 8, ad Exsuperium, Episcopum Tolosanum, 20 February 405, PL 20,495
- “If the Pope were to deny that the death penalty could be an exercise of retributive justice, he would be overthrowing the tradition of two millenia of Catholic thought, denying the teaching of several previous popes, and contradicting the teaching of Scripture.” -Avery Cardinal Dulles
God/Jesus: ‘Honor your father and your mother,’ and ‘Whoever curses father or mother must certainly be put to death.’ Matthew 15:4
This is a New Testament command, which references several of the same from the OT.
Jesus: "So Pilate said to (Jesus), “Do you not speak to me? Do you not know that I have power to release you and I have power to crucify you?” Jesus answered (him), “You would have no power over me if it had not been given to you from above.” John 19:10-11
Jesus: Now one of the criminals hanging there reviled Jesus, saying, “Are you not the Messiah? Save yourself and us.” The other, however, rebuking him, said in reply, “Have you no fear of God, for you are subject to the same condemnation? And indeed, we have been condemned justly, for the sentence we received corresponds to our crimes, but this man has done nothing criminal.” Then he said, “Jesus, remember me when you come into your kingdom.” (Jesus) replied to him, “Amen, I say to you, today you will be with me in Paradise.” Luke 23: 39-43
It is not the nature of our deaths, but the state of salvation at the time of death which is most important.
Jesus: “You have heard the ancients were told, ˜YOU SHALL NOT COMMIT MURDER” and “Whoever commits murder shall be liable to the court”. But I say to you that everyone who is angry with his brother shall be guilty before the court; and whoever shall say to his brother, “Raca”, shall be guilty before the supreme court and whoever shall say, “You fool”, shall be guilty enough to go into fiery hell." Matthew 5:17-22.
Firery hell is a considerable more severe sanction than any earthly death.
The Holy Spirit: God, through the power and justice of the Holy Spirit, executed both Ananias and his wife, Saphira. Their crime? Lying to the Holy Spirit - to God - through Peter. Acts 5:1-11.
No trial, no appeals, just death on the spot.
God: “You shall not accept indemnity in place of the life of a murderer who deserves the death penalty; he must be put to death.” Numbers 35:31 (NAB) full context

For some crimes, there is no mitigation from a death sentence.
