Given that Gen 9:6 says precisely the opposite I’m not sure how you can hold to that opinion. The Church interprets that passage to mean just what it says.

You are correct. The Catechism has major problems with Genesis, among others’.
The foundation of the death penalty is found in Genesis and is, based, specifically, upon “shedding blood”.
The Catechism got rid of the"bloodless means" language that was, originally, in the Catechism and which was, specifically, referenced by Pope John Paul II(PJPII) in Evangelium Vitae (EV) in the context of the non amended Catechism.
Context suggests “bloodless means” was removed in the amended Catechism because of its obvious and embarrassing conflict with the Genesis passage.
The Catechism was amended, specifically, to insert PJPII’s death penalty comments within EV, and that “bloodless means” was specifically removed from the original Catechism, even though PJPII referenced it in EV.
It appears that the amendment was used as a convenient (sneeky?) method to remove the improper “bloodless means”, even though an amendment, truly based upon PJPII’s EV, would have required that it remain.
The 2267 amendment replaced it with "If, however, non-lethal means are sufficient to defend and protect people’s safety from the aggressor, authority will limit itself to such means, as these are more in keeping with the concrete conditions of the common good and more in conformity with the dignity of the human person. "
“Non-lethal” is simply a conspicuous way to avoid using “bloodless means”, but it is the exact same meaning and therefore, irreconcilably, contradicts Genesis.
Catechisms should not have such tricks within them.
In addition, the “more in keeping with the concrete conditions of the common good and more in conformity with the dignity of the human person.” are a humanist base, not a biblical one.
Biblically, theologically and traditionally, the death penalty, certainly, is in keeping with “the common good and with the dignity of the human person.”
Even humanistically, we can see how execution is more in keeping with the common good and more supportive of human dignity.
More on that, below.
In 2265 we have “Legitimate defense can be not only be a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm.”
To repeat: “the common good” “requires” that an unjust aggressor be rendered “unable” to cause harm."
With individual murderers such requirement is only met with the death penalty. Only dead murderers are incapable of causing harm - a rational truism.
In 2266: “The efforts of the state to curb the spread of behavior harmful to people’s rights and to the basic rules of civil society correspond to the requirement of safeguarding the common good.”
The requirement is that the “common good” “requires” an unjust aggressor be rendered unable to cause harm." Again,with individual murderers such requirement is only met with the death penalty.
2266 continues: “Legitimate public authority has the right and the duty to inflict punishment proportionate to the gravity of the offense.”
Biblically, we know the death penalty is proportionate to murder.
2266 continues: “Punishment has the primary aim of redressing the disorder introduced by the offense. When it is willingly accepted by the guilty party, it assumes the value of expiation. Punishment then, in addition to defending public order and protecting people’s safety, has a medicinal purpose: as far as possible, it must contribute to the correction of the guilty party.”
Expiation, though a gift from God, must be seized by the guilty party. It is arguable, as per Aquinas and Augustine, that the death penalty is better apt to provide that correction and is, therefore, more in tune with the eternal aspects of the wrongdoers salvation.
From 2267: “the traditional teaching of the Church does not exclude recourse to the death penalty, if this is the only possible way of effectively defending human lives against the unjust aggressor.”
That is, most certainly, not the traditional teaching of the Church. Such teachings include , among others, that when committing murder, the offending party has forfeit their right to live.
In addition, another mess awaits: there is a major conflict between 1) “the traditional teaching of the Church does not exclude recourse to the death penalty, if this is the only possible way of effectively defending human lives against the unjust aggressor.” and 2) the “common good” “requires” an unjust aggressor be rendered unable to cause harm."
(1) states that use of the death penalty is just “if it is the only ‘possible’ way of defending human lives against the unjust aggressor”
but
(2) “requires” the death penalty as it is the only method of rendering an unjust aggressor unable to cause harm.
(1) deals with “possibilities” (2) with “requirements”.
Requirments rule over possibilities.
This obvious conflict shouldn’t exist within the Catechism and shows how poorly considered this topic was.
To make more of a mess, 2267 continues: "Today, in fact, as a consequence of the possibilities which the state has for effectively preventing crime, by rendering one who has committed an offense incapable of doing harm–without definitively taking away from him the possibility of redeeming himself–the cases in which the execution of the offender is an absolute necessity ‘are rare, if not practically non-existent.’ (NT: John Paul II, Evangelium vitae 56)
More of the “possibilities” nonsense, connected to the “possibilities” addressed in (1), above.
It is such a badly considered prudential judgement as to negate its “prudential” moniker. All jails, all prisons, all cities, all states, all countries have widely varying degrees of prison security. Even in the US murderers escape, murder in prison and are given such leeway as to murder, again, because of mercy, leniency and irresponsibility to murderers, who are released to causes catastrophic losses to the innocent when they are harmed and murdered by these repeat offenders.
Absent from the discussion is the harm to “innocent” murder victims and potential murder victims and the effects on their earthly and eternal lives.
Again, the only way to, humanly, make a criminal “incapable of doing harm” is to execute them. Rationally, there is no other way.
