Why is Capital Punishment important for nations to practice in terms of justice?

Every nation in the world must practice capital punishment.  The Holy Bible demands the death penalty as an important part of the justice system that nations must practice.

The Roman Catholic Church is in direct rebellion against the Holy Bible in opposing the death penalty.  It is wrong to oppose the death penalty because the Old Testament and the New Testament both demand it as a justice measure of countries.

Why has the Roman Catholic Church gone so wrong on the issue of the death penalty?  It is because the Vatican follows the Pope, rather than the Holy Bible.  The Holy Bible clearly demands the death penalty as a justice system of the courts and of nations.

Sanctity of life is an idea that was created by the Roman Catholic Church.  The Holy Bible does not teach sanctity of human life.  If human life had sanctity, God would not haphazardly kill humans for sin, such as after the Israelite worship of the Golden Calf.  One act of idolatry resulted in God’s direct issue of death as justice against the Chosen People.

Abortion is wrong because it violates the Ten Commandments, not because there is sanctity of life.
