You want to do something while having no idea whatsoever how to do it. There is no healing psychopaths. There are upper class criminals too. Economical status does not define ones character. Upper class criminals usually avoid violence because they have better means of enriching themselves illegally, meanwhile the poor ones need to resort to robing, killing and trafficking guns/drugs.
Your idea is more repression, more violence and less compassion. You have absolutely no clue about the real implication and systemic reasons behind those violence. You are like blind man trying to put out a fire with a machine gun.
You are talking about severe cases of psychopathy. It's 1 % of the population. It has absolutely NOTHING to do with the problem of your country. The reason people seek violence in south America is not psychopathy, it's structural, economical and societal reasons. You are focusing on a strawman to avoid trying to find solutions and calm your thirst for violence.
