The Bible (well, the New Testament at least ) lacks bloodthirstiness in its heroes and God, and yet that did not change the bloodthirsty course of history (and indeed, in some cases, was used as a basis for violence and persecution). So, in that respect at least, I don't believe that it would have changed the course of history much.
