Re: Why did the League of Shadows want to destroy a peaceful city?
I think if anything Bane was trying to show he was more than both Bruce and Ras. He even says "I am the League of Shadows". He was trying to prove himself. This is very similar to Banes motivation in Knightfall which was to show he could best the Batman for the sake of it. I don't see how his motivation is anymore unusual than that.
