Whatever you think of de Sade, he was a complex figure and we should not look for easy answers with him. He was, strangely perhaps, against the death penalty, and he was never put in prison for murders or anything like that.
If you treat prisoners well, they will be less angry, less inclined to violence inside prison, less likely to provoke violent actions by guards, less likely to have reason to file brutality lawsuits that cost taxpayers a bundle and waste administrators' time. And most important, well-treated prisoners will be less likely to leave prison angrier, more vicious and more inclined to criminal behavior than when they went in.
Money will determine whether the accused goes to prison or walks out of the courtroom a free man.
Justice is that virtue of the soul which is distributive according to desert.
