Wayne, as Batman, deliver this line to Harvey Dent.
Is this really true? Wayne had suffered horrific tragedy in his past at the hands of criminals, and he was hurt just as badly by Rachel's death as Harvey was.
Yet the Joker even admits that Batman is "truly incorruptible". It's obvious that Wayne can endure more than Dent, isn't it?
Now, maybe Dent was the most idealistic of Gordon, Dent, and Batman, but that's something different IMO.

I don't even know where you're going with this? The thread asks a specific purpose, within, is a specific quote from the movie, which was directed towards Harvey, before he became Two-Face.
Why do you think Batman stopped Harvey when he was threatening one of Joker's thugs in the alley? He basically gave him the same speech there.
But that was the entire point with Bruce Wayne. He thought he was the best man for the job, as he even shared his feelings with Rachel at the dinner party, and why he was going to retire Batman. That was a major point in the movie! Yes, Batman was trying to talk Two-Face out of shooting the kid, but that doesn't mean he didn't mean it, as it was a major theme throughout the ENTIRE movie. And Batman did tell Harvey what he thought of him, when Harvey had a gun to Thomas Shifts face in the alley, when he said, "You're the symbol of hope I can never be". Meaning: he is a better hero for Gotham, even more then Batman himself.
