All of this is complete and utter conjecture and not touched upon once in the whole movie.Where did Bane ever equate his life to Talia's? Or hers to his? Where did Bane ever even talk about his past beyond saying he was born in darkness?
You can only present what the movie tells you or show you.
		
		
	 
Why is it so hard to believe Bane felt a connection to innocent child born into a prison for nothing? First off, she's a child....even hardened murderers will kill child rapists in prison. A child that grows up in same circumstances as you...and you are presented an opportunity to give her a better life than you got...that seems quite reasonable for Bane to relate to her.
You allow her to escape the prison....and then she returns unexpectedly to save you and heal you....even that can break the most self-hating hardened criminal. Her army gives him an opportunity to develop, grow, train...a means to release his frustration and exercise control over his life...you don't think a unshaken loyalty that permeates from the depths of his psychosis or soul to her? Talia was a light (in his mind) in the pit of hell...and that light rewarded him with freedom and dignity...you are surprised that Bane would equate his life to hers? When Talia utters that "Bane's only crime...was that he loved me..." did you see the tears in his eyes? No matter how many beating he took...he's willing to do anything for this friend?  
	
	
		
		
			Again this is untrue. Talia clarified this definitively when she said Bane was excommunicated because he was a reminder to Ra's about what happened to his wife in the pit. Nothing to do with him being too extreme.
		
		
	 
So Ra rescued Bane at request of his daughter...from the pit.
So Ra hired Bane into his army and tried to heal his wounds...Bane became an excellent subordinate. Then Ra excommunicated him...because he was a reminder of what happened to his family...not because of anything Bane did? 
Does that really make more sense than Alfred's research?
Is Talia's explanation the true reason...or is she trying to psychoanalyze her daddy? 
Perhaps we, should dig deeper. 
 
	
	
		
		
			He couldn't work with the Police because he was being hunted by them for Harvey Dent's murder. Gordon was laid up in hospital.
What other options did he have? Sit back and let Bane do what ever he wanted? This wasn't a situation where a charitable donation to the police fund is going to help.
		
		
	 
He could have worked with Gordon more closely...allowed Gordon to be voice of reason to his police department in creating a strategy. He didn't have to go brawl out it in a sewer. 
	
	
		
		
			Yes, but the key difference is two of the villains were in a city with an overwhelming amount of corruption. Bane and Talia were not. So there was justifications and logic in the ideals of Ra's and Joker.
		
		
	 
There was still corruption in Gotham although the details aren't discussed heavily. Gotham was becoming a police state and using heavy handed prosecution techniques to convict people. The price to pay for "safety" is lost liberty and eroding rights. The background of this climate is depressing economy which was leaving   Would you want to live in North Korea?
Despite this heavy handedness of police state brutality, Dagget was confident enough to pull off the biggest example of financial theft and fraud in Gotham's history....funding overseas wanted mercenaries!! Dagget didn't fear the police at all during whole exchange...his only fear was Batman's return. Why would a wealthy man like that carry out that sort of plan unless he was confident he was pretty untouchable. The power was moving from low-level mob bosses to highly politically connected and wealthy. 
The mayor sees example of budding gang growing in sewers,...and instead of accepting it head on...tries to cover it up to create an illusion of safety!
The level of corruption was compressing towards top during this period. 
LOS didn't care for political presentations...they cared about the innate state of Gotham City's social and political climate...and used it to their advantage.
Even though LOS imprisoned the wealthy during their reign....there was still common people participating in the riots and looting of private property at Bane's request.   One warlord seizes control..and people happily break out into riots at his request? 
It wasn't just the LOS shouting for political prisoners to be executed by exile through Dr. Crane's "trial"...it was mobs of regular common Gotham City in the audience. People who look like you or me shouting for people falsely or frivolously accused to be executed....simply because the mob would be rewarded monetarily.
Doesn't that show how thinly veiled the social angst exists in that city?
	
	
		
		
			Selina is a thief, every city has thieves. Selina was not desperate, she just wanted a brand new life with the clean slate device. She couldn't start fresh because her past was always catching up to her.  Every city has poor people, homeless people etc. It doesn't mean there is a massive class division.
		
		
	 
	
	
		
		
			Where was this class division in TDKR beyond Selina saying that the rich are all fat cats who just take take take?
		
		
	 
	
	
		
		
			What corruption in the administration was the LOS aware of? None at all.
		
		
	 
How do you know this? How do you know what Talia or other LOS spies do or don't know about Gotham's operations? And even if you had no evidence....do you always believe there is no corruption afoot with your political enemies just because you don't have concrete evidence in front of you? Its human nature to believe your political enemies are behaving deceptively. Look at the last few presidential elections and reactions in media punditry.
