While I found Sunil Dutta's article engaging and one that certainly captured the essence of the death penalty miasma, I think it missed one salient point: the dehumanizing nature of the act.
Death penalty opponents often lose those they wish to convert because they speak too much about what the penalty does to the people on death row, the ones for whom their audience has little sympathy (rightly or wrongly) in the first place. They should instead focus more attention on what it does to the soul of the nation that engages in the death penalty. Isn't it a mark of our failure that we even feel compelled to engage in such a barbaric practice in the first place? Isn't the most powerful democracy in the history of the world simply better than this?
