Not every crime can sufficiently be paid in the scope of one lifetime and more importantly not every person can be rendered safe for the rest of society in any finite term. I don't think its incompatible with the notion of justice to suppose that someone can represent an inextinguishable risk to society despite serving their sentence. Rather than questioning the entire concept of justice one can simply question whether the implementation of justice is in this instance sufficiently sound. To give an extreme example its probably best that the prolific serial killer Gary Ridgeway remain in prison until he's dead. If our justice system were dumb enough to release him one wouldn't be obliged to accept or reject the entire concept of justice as one piece. One could simply reject whether Gary was a safe fellow to be around. This isn't even hypothetical there are actually serial killers who are free men post conviction. https://www.ibtimes.com/brazils-most-notorious-serial-killer-free-man-despite-71-murders-out-prison-3335424 https://www.ibtimes.com/brazils-most-notorious-serial-killer...
