Society as a whole is not wholly responsible. Some people are taught and some are just bad - bad brains, bad choices, bad intents. I've never had to teach a toddler what to do when another child takes their toy. Somethings are just innate. Some can be helped and should be, others cannot. Taking away an individual's responsibility removes dignity and gets in the way of healing. We don't have to give into the fallacy of choosing one or the other - both society and the individual can be responsible for their actions.
But yes, we have been devaluing human life and dignity, or if you prefer the Image of God, across all of society. The conditions of these prisons should not exist even if this is purely punitive, which I do not believe it should be. Victims deserve justice, but criminals deserve the right to pay the price and come out "clean". We should want to make society whole, to bring them back into the fold as full members, but too often we don't want to pay the cost.
