I really do not know why people would associate a book with evil. How ever abominable Hitler was, his book is, after all, a book. Just like we are curious to know about a hero's life, there is curiosity as to a villain's life and the reason behind their villainy. I really do not think we should make such an issue of a book being there on the shelf. He is not going to come back to life if the book is read and no difference is made to him if his book is not read. We should take the issue purely in an academic context and should not detest a book just because the writer's deed were too ugly.
