The reasons why they want to destroy a peaceful city are fan-fiction?
The answer that the movie gave was that despite the extermination of organized crime (mob), Gotham (and perhaps all of the West, in the eyes of the League) was still (or perhaps increasingly) full of white-collar corruption, giving way to large wealth gaps, high unemployment, etc.
