I think generally this term is used for repeat offenders who never learn, don't want to learn and couldn't care less.

As for punishment....hmm we don't punish "adults" with corporal and capital punishments so for kids it would be wrong....and it goes against all that human rights mumbo jumbo.
As good as capital punishment sounds for clearing jails and giving very deserved deaths to certain people it isnt a perfect system
Just have to look at the USA and see that it is far from an ideal system and definitely does nothing to stop criminals in a deterrent sense
