Maybe some of you have watched the movie "Seven", about this guy (John Doe) who did a serial killings based on the seven deadly sins idea of Thomas Aquinas and/or St Augustine.
And Canterbury Tales is used as one of the refference by Detective Sommerset (starring Morgan Freeman) to understand the psychopatic killer.
So it makes me wonder, I mean Canterbury tales are filled with nice harmless stories. I mean the idea of purgatory or, paradise lost, may influenced someone's thought..but the Canterbury tales?
