It seems to me that the more Christian a country is the less likely it is to regard the death penalty as immoral. Abolition has taken its firmest hold in post-Christian Europe, and has least support in the church-going United States. I attribute that to the fact that, for the believing Christian, death is no big deal. Intentionally killing an innocent person is a big deal: it is a grave sin, which causes one to lose his soul. But losing this life, in exchange for the next? The Christian attitude is reflected in the words Robert Bolt's play has Thomas More saying to the headsman: 'Friend, be not afraid of your office. You send me to God'. For the nonbeliever, on the other hand, to deprive a man of his life is to end his existence.
