It seems to me like the Catholic Church has improved exponentially since parishioners were not burned for possessing the bible in their native language and the days of the St. Bartholomew's Day Massacre are long gone. I don't think replacing the pope would change anything. Allowing priests to marry would go a log ways to resolving the root cause of things. In a discussion with a cranky uncle the issue of priest marriage came up. He said not only should they be allowed to marry, but it should be a requirement.
