Answer: Concentration camps were SOOO much worst than a regular jail or prison. jews and people of other races were tortured in unthinkable ways and countless of inoccent people were killed for no reason. These people were hardly ever feed and only received enough to keep them barily alive. They were forced to do ruthless labor and to do sick, and crual acts just to not be thrown into gas chambers, or burnt alive in the crematoriums. when these peoples lives were taken they would just be thrown into a mass grave of countless other victim without a service. While a jail or prison feeds prisoners and treats them humanly. Prisons also allow them basic human rights and visits from family and etc.
