If I were asked to chose between execution and life in prison I would, of course, chose the latter. It's better to live somehow than not at all.
Capital punishment kills immediately, whereas lifetime imprisonment does so slowly. Which executioner is more humane? The one whokills you in a few minutes, or the one who wrests your life from you in the course of many years?
It is not only the prisoners who grow coarse and hardened from corporal punishment, but those as well who perpetrate the act or are present to witness it.
It is the writer's business not to accuse and not to prosecute, but to champion the guilty, once they are condemned and suffer punishment.
