2. There is No Hope in Crime Alley

Detective Comics # 457 (1976)

Here's another famous classic.

In this story, on the anniversary of his parents' deaths, Batman returns to Crime Alley to visit Dr. Leslie Thompkins. He apparently does this every year and has made an impact on the neighborhood by doing so. Dr. Thompkins has devoted her life to community work, helping the city one person at a time. After Batman finds her and talks to her a bit, we learn why he's there: on the night his parents died, Dr. Thompkins was the person who consoled him and helped him through that horrible experience.

At the end of the night, Batman asks her why she helps the community the way she does. She responds that many years ago she witnessed a young boy lose his parents to a robbery gone wrong. Seeing that horrible event made her devote her life to reforming the city, to ensure that it never happen again. And it's a really wonderful moment. Seeing someone else witness the same tragedy and respond to it with a completely different method of do-gooding. It's earnest and sweet and good.

One of the Greatest Batman Comics of All Time?: I think so. It deserves to be in here.
