Neither abortion nor the death penalty are black and white, though one might think so considering they deal with life and death.
I am pro-life, but I believe the goal of 100 percent prevention or banning of abortions is an impossibility. We have never lived in a country which had a 100 percent ban or prevention. To pursue that goal is to risk tunnel vision which blocks out more achievable goals.
For instance, nearly half of all abortions are the result no birth control of any kind being used during the sex act which led to the unintended pregnancy. This means an effort to educate people on the uses of birth control, and get them to actually use them, and use them correctly, would result in many millions of fewer abortions each decade.
While the rate of abortions has declined since Roe v. Wade, it has not declined anywhere near enough, and I believe that is in large part because we have allowed the extremists suffering from tunnel vision to control the dialogue, with the result of virtually getting nowhere.
As for the death penalty, many of our Christian churches teach it is wrong, and some Christian faiths are even very public in their opposition. But it seems quite a few right wing adherents who wear their Christianity on their sleeves conveniently forget this.
I, personally, probably would not hesitate to pull the switch on an animal who killed someone I loved. But our justice system exists to distribute justice, which is quite frequently at odds with our passions.
I know my passions can get away from me, and I would love to be able to defer to our justice system and trust it will mitigate not only my own zeal, but the zeal of our whole society so our society may exist in the first place. However, careful observation and examination of our justice system has revealed to me the death penalty is meted out quite unjustly and in a very imbalanced fashion.
Not only that, many men on death row have been found to be innocent, thanks in large part to the advances of science and forensics. So something is clearly broken.
Therefore, at this juncture in my life, I am more favorable to life sentences without parole. That this opinion aligns with what my faith teaches is an added bonus.
Those who argue the economics of the death penalty miss the point. To demonstrate the illogic of the argument which says it is cheaper to keep someone in prison for life than it is too execute them, one only has to provide reductio ad absurdum and point out it is cheaper to let a murderer go free than to imprison him for life.
You cannot put a price on justice.
