"“This is absolutely a Batman story,” he emphasises. “It’s about Batman facing his greatest fear, and it’s a fear he was unaware of: failure. All Batman is trying to do is win a war. All he’s trying to do is right wrongs, beginning with the death of his parents and followed by another seminal event in his life, the loss of his partner, Jason Todd [who replaced Dick Grayson as his sidekick, Robin]. It was a major mistake in his life, bringing another kid into this war. So for Batman, it seems like one horrible mistake after another.”"
