This make me heart sick! Many of the young and middle aged men who went to prison in WWII, those that spent time in very high-risk prisons came out still looking over their shoulders for the guards. Even those than were sent to low-risk camps, came out carrying it in their "shoulders".
Then there was cruel rejection by former school mates, relatives and neighbors after being released. Of course, don't forget that most were on parole for a time afterwards and sometimes the draft board would be looking for ways to send them back to prison. One young man was sentenced twice, after he served four years, he was sentenced to another fours years.
I remember a man who went to prison in WWII and was in tears that his son was serving time in a very harsh prison during the Korean Conflict.
WWII was a response against a definite evil; and most definetly a terrible and cruel war. And the public had little sympathy for those that didn't serve.
