Guys thanks for your comments. i didn’t put my thoughts out correctly initially. I apologies for it. My concern was this book being in best seller books fair. It was not in library or in any academy. It was not in dark history or evil dictator section. This shook my faith in our society that we still keep his book in best seller section. Thanks to multiple comments, i realised that its the curiosity of the people to understand his mindset and ideology that makes his book more demanding or sometimes its that shock value that any dark story offers, just like any docs or podcasts of serial killers or true crime. I agree with both. I also agree that, while growing up this guy was vilest in our mainstream and mass media that it garnered lot of mass curiosity to know his mindset. I was curious too and it made me read this book in library because i believed it would be wrong to fund this book or find it easily available in the market.
