Learning About Concentration Camps

In my ELA class I have been recently learning more about the Holocaust and concentration camps. I always knew that they were harsh places but I didn't think they were as bad as they are. I learned that they would burn people alive to kill them. Among those people were a lot of children and babies. It seems so horrible that people had to live like that and people could actually treat others in that way. I would never be able to live with myself if I did something like that.
