For 2000 years the Catholic Church has recognized that abortion and capital punishment are very different. Seems the good Bishop doesn’t understand that
Life for the innocent
Death for the guilty
CCC 2267
excerpt: 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 to the dignity of the human person.
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 definitely taking away from him the possibility of redeeming himself - the cases in which the execution of the offender is an absolute necessity “are very rare, if not practically nonexistent.”68
the death penalty is just that... a penalty. it happens to be a deterrent of future crimes by the penalized and may serve as a deterrent to future criminals. it is not cruel and unusual punishment, it is a penalty.
sometimes criminals need killing. and G-d wasn’t against killing, he warned against committing murder.
