It's interesting to note that Mengele refers to himself in the 3rd person as "Andreas". This is a classic sign of a pompous and manipulative character.
A person that refers to himself in the third person is thinking of how you perceive him. He’s looking at himself, while you’re looking at him, so that he can modify how he appears to you to get the best result he wants from you. A person that is so self absorbed and focused on himself that he actually sees the "HIM" he’s created as separate from himself so much to cease using the word "I", is too busy trying to invent himself to "BE" himself. Hence, people that refer to themselves in the 3rd person (and aren't mentally ill or challanged), should earn some of the same caution that people with shifty eyes earn. It's abnormal behaviour, and probably a lucky view into the mind of someone who got where they are by being quite manipulative.
As far as burning the books goes, that makes you as bad as the Nazi's doesn't it? Far better they are bought by, or on behalf of, a Holocaust Museum or Foundation, where careful study may elucidate the inner thoughts and workings of one of the Final Solution's prime movers and as such benefit us all as to some of the reasons behind this atrocity.
