No book ever killed anyone.
Actually, books and ideas kill innocents all the time, though they use humans as their agents. Sometimes the books and ideas are direct in their aims, and sometimes subtle and innocent looking. Evil people very seldom have libraries filled with Nancy Drew mysteries and CD shelves stocked with The Carpenters, Big Band and Ozark dulcimer recordings.
How many tens of millions died because of three books?
1.) “Das Kapital”
2.) “The Communist Manifesto”
3.) “Mein Kampf”
