Sure but their mental illness is a symptom of capitalism and even most of those people can be helped if that was what resources were being spent on. As a person who has a lot of experience working in community with killers, pimps, drug dealers, addicts, etc. I really know most people are not beyond reach and that we have the technology and resources to reintegrate them into society. Look at the Chinese approach to salafism, mostly it was education and job training to get the majority of people back into society. USians are an extreme case and need a lot of therapy and support but there is no reason to think that 95% of "criminals" aren't in that position because of capitalist indoctrination and can't be helped . The types of truly sociopathic people you are talking about are very few compared to most people in prisons
drunk driving and has caused a fatal wreck, people who do multiple robberies, shootings, home burglaries, sex crimes, etc.
