I see, yeah I had very similar feelings. I went to Majdanek in Lublin and some other camps a few years later and learned about the very early years of the SS and Gestapo and how they got "training" from their brothers at NKVD (among other places at the infamous Ljubljanka prisons in Moscow) which later became the KGB on how to interrogate and torture their victims. That's when it really hit me how close the Nationalist Socialist German Workers Party aka the Nazi party stood to the Communist party despite their attempts to portray themselves as an anti-communist patriotic movement. Either way, I think everyone should visit those camps because we should never forget...Note: I had my first trip to Europe (basically) last summer. We went to 11 cities/towns in Poland and Rome.
I visited the camp. I really "enjoyed" the visit to the camp. It made me want to kill everyone (very slowly) who helped build, run, or support the camp. It was SICK how some German companies had advertised the work they did to build the camp.
I was very impressed that some local Poles had set up volunteer committees to help the victims of the camp, and surprised that the Nazis had let them give aid to the prisoners.
