Otto had also traveled extensively with his family. No doubt he believed that traveling -- even to remote areas of the globe -- was not challenging in the least. He was comfortable visiting increasingly foreign lands, I recall reading. His parents were with him (one or both) on all his early visits.
And yes, it is true that he went to the floor that was verboten. After all, as described, he was intelligent and highly curious. Perhaps he wanted to see what was there that was so dangerous to be seen. No one knows.
But kids, eh? I think Otto was used to being excused for small and innocent rebellious acts as many of our nation's children are. Not that there is anything wrong with that. It must have been a horror movie come to life for poor Otto when he realized that the powers in the land he was visiting had a sick and perverted sense of power and of what is right and wrong. A child of well-off parents, living in suburbia and then studying at a selective university whose grounds are the stuff made for a scholar's dreams suddenly forced to endure hard labor and torture. What a nightmare! What a h___ on Earth!
Subjected to torture for hideous reasons! I could not have endured this, and I am certain this sensitive boy suffered mightily.
