I think it's really cool for people to actaully go to those places and visit history! Yes it was horrible but to make sure stuff like this never happens we need to learn about this. I recently read a book called a Man's Search For Meaning. It's about a man living in the concentration camps. He tells in the story of how the Nazi's try and dehumnize them, and in the book explaining some of the most horrible conditions. And he realizes from this expereince that how he choose to suffering brought meaning and purpose.

Anyways it's a super interesting book. Its by Viktor Frankl. Awesome post man.
