The majority of the guests had disapproved of the death penalty. In the opinion of some of them, the death penalty ought to be replaced by imprisonment for life. The narrator had prefered being killed in a few minutes to drag the life out of himself in the course of many years. However a young lawyer had not agreed with him, he had tought that to live anyhow had been better than not at all. Then, the narrator their host had been carried away by excitement, he would bet him two millions he wouldn't stay in solitary confinement for five years.
