I'm not sure Robert Moses knew that. He wasn't an urban planner. He was an urban doer. He made it his life's mission to not learn the actual impact of his work on people's lives. I suspect he took that willful ignorance to his grave.
I didn't mean it in a way that absolves him of responsibility. I mean that he purposefully shut out any information that undermined his self-image as a "great man." That's a form of evil. It's worth differentiating that from other kinds of evil, as I believe it may be the most common.
