Gotham City needs a savior. The people need someone they can relate to and they can praise. In the movie [The Dark Knight], Batman claims to be that savior. Batman struggles, cries, and almost gives up, but he never does. He will do whatever it takes to save Gotham, whatever the price is, whether it's for the criminals or for himself. Even though they needed a savior they did not want to accapt one. Despite being rejected by the citizens of Gotham City, [Bruce Wayne], who plays the role of Batman, decides to be the savior that the people of Gothom City need.
Batman sacrifices himself, this makes him the Christ-like figure of Gothom City. Just like Christ, Bruce Wayne had a wealthy family who loved him. Though Christ did not lose anyone, he saw that his creation needed to be rescued. Bruce Wayne saw that the people of Gothom City needed to be rescued from all the evil that was going on. All the crime that the Joker was doing and all the killing and theft that was going on. Besides sacrificing his own safety, comfort, and well-being, in The Dark Knight Batman sacrifices his reputation. Bruce Wayne-Batman does this by defining himself as a legend. By doing this he is sacrificing himself. Batman takes the blame of others on himself. He does this because he knows that he is capable of taking on the wrath and the sinful desires of the citizens of Gotham City.
Like Christ, Batman was despised and rejected by his people. Just like Batman, Christ came to help and rescue his people. But with man's sinful hearts and their desire to be in control of their own life, they denied him. Surely he took up our infirmities and carried our sorrows, yet we considered him stricken by God, smitten by him, and afflicted" (Isaiah 53:3-4). Just because Batman hasn't physically sacrificed himself to the point of death does not mean that he isnt a hero.
