It's not, at all, a barbaric practice, it is a flawed and potentially tyrannical practice.
So, you are supportive of the concept but not the practice. I can use that for my entire reason to have changed my cap punishment position.
Its kind of like the concept of a "just War"
I am indeed supportive of the concept but not the practice.
What you do with this revelation is up to you, but give credit where credit is due if I have helped you resolve an intellectual conundrum.
I don't, at all, see how it is like the concept of a "Just War," or war in general.
There are absolute alternatives to the death penalty. There are not always the same for war.
Trying to transpose my argument against the death penalty to an argument against war is specious.
Let's use WWII as an example of a "Just War"
Japan attacked the US. We can argue all day as to whether or not Pearl Harbor was the forerunner of a threat to the American homeland, but for those who lived in America at the time, it was reasonable to assume it was.
Based on that assumption, there was no alternative to war other than eventual surrender. This, clearly, doesn't match the alternatives involved with apprehended murderers.
In the the case of the murderer, the choice isn't to let the monster go free and endure his or her predations, its how to deal with the monster.
We also went to war with Germany. Putting aside the fact that Germany declared war on us, it, again, was reasonable to assume that Germany presented an eventual threat to our homeland.
Do you, for a minute, think that if Hitler had been successful dominating all of Europe, the Soviet Union and Africa, that he wouldn't have eventually found it necessary
to invade the US?
Here again the alternative to going to war with Germany was doing nothing, not an alternate method of dealing with the threat.
The notion of a "Just" war is somewhat ridiculous. With the exception of wars started solely for the purpose of expanding the personal power of an individual, they can all be justified. To the extent they are actually justified it is because there is no reasonably acceptable alternative.
There is, to repeat myself, a reasonably acceptable alternative to capital punishment.
