Why do people act as if the bible is good and claim that it is true?

The bible is like a book of sadistic fairy tales that was written by different writers, with different beliefs, edited and changed over time. The Catholic Church; had commitee like meetings in the past to decide what to believe and what to kick out. Also, Christians pick and chose what content they want to follow and use sin as an excuse. Does anyone actually read it and see all of the hate and prejudice it contains? How can someone jurisidict the wars and killings that stemmed from it's verses? Logic does not reside inside of it's pages. With all of these problems, why do people constantly use faith as if it is equivalent to fact rather than a blind person's attempt to explain the unknown?
