What Happens to Human Beings in Concentration Camps?

Concentration camps are every person’s nightmare. They are camps organized to experiment on people and play with the lives of humans, as to turn them into some animal. These concentration camps are deprived of life; they are out of the real world. People in these camps have no life, it is as if they were already dead. Reading about what happened in these camps I can only imagine how frightening it was to be in these camps. To have no life or value. To be deprived of life itself. It is like dying then coming back to life.
People in these camps had no idea of whether what happened to them was reality or just an illusion. They had no sense as to what life was or is. They were like a new-born, with no insight on human life. Concentration camps were formed by extremist that believed in world domination. They used people to experiment with, and to them these people had no life already. It was as if these people were already dead.
For example the Nazi’s had concentration camps that were horrifying to even imagine. They tortured people left and right, they deprived them of everything. In a way to starve them to death, others died because of hygiene and some because of the over population. The Nazi’s weren’t the only people to have concentration camps, as I recall the United States had some also. These camps had no belief of mercy and justice. They had no value or meaning to human life, but their own.
