There was different types of camps. For example, in the extermination camps the Nazis lied. They would tell the Jews to undress so you could take a shower but they actually killed them. Those where the rules. Concentration camps were meant to work and to starve prisoners, thats how the concentration camps usually were. They didn't care either, if the Jews died they could just replace them in a blink of an eye. The Germans made all kids go straight in the gas chambers so they die and won't produce more Jews. They also made most pregnant ladies go to the gas chambers so the baby and woman die. Hitler forced Nazis to capture all Jews and send them to the concentration camps with bad transportation on a crowded train for 3 months and then separate them from the family, and give them back with no clothes.
