To consider whether the Bible or part of the Bible can accomplish good in this way, it is helpful to compare it to other books that actually have accomplished good.
To Kill a Mockingbird is on many lists of the top 100 books of the 20th century (from the Boston Public Library: http://www.bpl.org/research/AdultBooklists/influential.htm). People report changing their lives for the good after reading this book. The book does not require belief. It requires serious consideration of thematic elements that apply in the real world. If a person is not willing to expend the effort to consider what the author has to say, nothing changes. It is difficult to conceive of someone becoming a worse person as a result of reading it.
How about the Bible? Readers are promised other-worldly rewards, but only if they believe that the contents of the book came from God. They therefore have a selfish incentive to accept the contents, even when these describe killing and maiming by God and his followers. It is not difficult to imagine bad results coming from a book like this. It is not necessary to detail the way the book has been abused.
Why is the Bible, and not To Kill a Mockingbird, abused like this? Because of the nature of the contents. If the authors/compilers wanted the Bible to make the world a better place, they did a very, very poor job. Indeed, one would have to consciously work to create a book that causes more discord.
It is possible to write books that are clear, thought-provoking, and beneficial to their readers. The Bible is simply not one of these books.
