"The history of Christianity is, of course, a prime example of how the belief that you are in sole possession of the truth, that is to say, right , can corrupt your actions and behavior to the point of insanity. For centuries, torturing and burning people alive if their opinion diverged even in the slightest from Church doctrine or narrow interpretations of scripture (the “Truth”) was considered right because the victims were “wrong.”"
