The two are not incompatible. You can lock up the people most likely to murder; before you solve all possible society causes and build perfect deterrence. I do know though, that your ability to build deterrence, or fix societal causes, will be heavily impaired to the point of impossibility if you don’t fix the marauder problem first. Deterrence is a preventative measure like brushing your teeth - but you can't brush your teeth later out of gingivitis after-the-fact. It’s like saying fixing corrupt nations need democracy. Maybe - but if the people are starving, that’s the first problem needing fixing, or the attempt at democratic reforms will certainly fail.
