Pop Frances changed Catholic catechism to totally reject executions. Here in the US the polls move from 80% to 35% for nailing people to a horizontal cross. About half of us. As you can well imagine, in the past year and a half it is now at the 55% high. With of course the most Christian Christians all for it. A religion based upon the horror of an execution. Makes no sense? None of it makes any sense.
When it comes down to the bottom line of morality, capital punishment is the issue of humanity.
