I think it's good when the audience questions Batman's sanity without having a clear answer.
He is not crazy like his rogue gallery but he is far from "normal". He is so driven, obsessed, focused, and methodical it borders on superhuman. Nolan suggested anyone could take Batman's place with noble intent but nothing could be further from the truth. Not only does it take incredible genes (physically/mentally), training, money and nobility but it takes a mind so scarred by tragedy that the mind focuses like a laser on self-perfection to repair the past that can never be repaired. So yeah it takes an abnormal mind to achieve what Batman achieves.
