Actor/director Eli Roth is no stranger to exploring the nature of evil.  As a master of horror with films like "Inglorious Basterds" and "Hostel," Roth turns his lens to research possibly the most horrifying monster of them all - the average American.  

In Curiosity's "How Evil are You?," Roth sets out to recreate the infamous Milgram experiment to see how, or if, the results have changed.  Roth himself even undergoes tests and scans to see if he carries what researchers dub "the evil gene."
