I mean, it depends on what you mean by "violently inclined".
I'm not a sociologist, so I don't know specifically what works and what doesn't, but clearly whatever we've been doing for the last 50 years has led to a smaller percentage of children born with inherently aggressive/antisocial personalities going on to commit violent crimes as an adult.
If you're talking about adults with violent inclinations that have acted on them and committed horrific crimes, then the obvious answer is to segregate them from the rest of society as they're clearly dangerous.
It looks like we're speaking across purposes. I'm not trying to absolve rapists and murderers of blame, nor am I trying to downplay the danger they pose to the rest of us. At the same time, though we should acknowledge that violent crime seems to be a mostly-solvable problem on a population level and simply throwing up your arms and saying "bad people are bad" isn't going to push the stats down.
Some get better, some are disasters waiting to happen.
Source: Norwegians do this. It is not every day it seems but there absolutely are multiple cases each years of people with violent pasts who become violent again given the opportunity.
There are two types of prison sentences here: ordinary and "forvaring" (best translation I could come up with is "detainment") which practically means they get to serve a minimum sentence anyway but won't be released until the specialists consider them reasonably safe. Kind of close to life but with a chance of parole, only the parole is meant to be the rule, not the exception.
For now it seems to work well enough, but if the rate climbs I think they will have to make adjustments.
