Perhaps someone should check if there has been any deterrence resulting from Saudi Arabia's barbaric justice system. After all, Singapore is just one city - and it hasn't deterred anyone there either.
And then, of course, there is the fine example of IS's barbaric justice system. No news of any deterrence there, although it has caused quite a few people to flee. Some are not so lucky.
Actually, this is quite off the mark. You end up in the justice system, because of having been found guilty of breaking a law - or, in certain cases, because of being suspected of having done so. Retribution, deterrence or any such nonsense has nothing to do with it.

Retribution is essential for justice and is a legitimate goal of a justice system.
