Christians, prove your minds aren't molested by fear.

[Angrboda]

No I'm talking about justice. Fairness. Just deserts. Where every crime gets what it deserves.

If you had said every criminal gets what he deserves, but then it opens the question up to multiple ways of dealing with criminals, depending on what the goal is. How you can make that balance of goals "perfect" must be a neat trick.

Crimes in themselves don't have just desserts. That's why we have sentencing hearings. To adjust the punishment to the unique circumstances of the criminal and his act.
