Actually Michael, it has been recognized that individuals who are incarcerated can be traumatized and even develop PTSD challenges. Anyone put in a situation where they are trapped and can't escape and experience abuse can end up struggling with mental health challenges that can add extra challenges to their ability to find a "healthier" place in humanity once that person finishes their sentence and is released. It is no secret that a lot of individuals that end up incarcerated had/have mental health issues that contributed to whatever they did that caused them to be incarcerated in the first place.
Sometimes the individual committed crimes because that individual had a severe addiction problem where they ended up stealing or even selling drugs to support their own addiction problem.
