I very much share this sentiment, I often think of prisons as quarantine. But that’s the descriptive dimension, not the normative.

Crime victims seem to crave “revenge”. It’s a very human thing. In fact psychological studies have shown it turns out that revenge feels quite fulfilling to the perpetrator. Societies without an institutionalized punitive systems (like much of western society has historically) tend to have family feuds which can last for generations.

I don’t think that should be a norm, bit plenty seem to think so, often quite strongly.
