With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us. Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?

New York City is legally required to provide shelter to anyone who needs it. But a new WNYC and Gothamist investigation finds that the Tillary Street Women’s Shelter in Downtown Brooklyn has become a place where violence, overdoses and chaos are part of daily life. WNYC and Gothamist editor Andrew Giambrone joins us to discuss months of reporting that uncovered more than 2,000 calls to 911 in a single year, hundreds of fights, and growing concerns from residents who say they did not feel safe inside one of the city’s largest shelters for women with mental illness and addiction.
