Re: Why did the League of Shadows want to destroy a peaceful city?
I will say this, the only way I can see the 'revenge' plot working from the perspective I've pointed too is that it's Bane who convinces Talia to do it as a means for him to take control of the LoS. She's loyal to him so it is plausible that he could convince her that this is what she should do.
Fanboys make excuses, real fans acknowledge screw-ups.
Do me a favour - don't break up my posts into multiple quotes when replying, I won't answer back.
