The allure of rogishness and transgression

Scott Lynch, author of The Republic of Thieves, joins Brandon, Howard, and Mary before a live audience at GenCon Indy to talk about roguishness. Why do we like rogues? What can a roguish character accomplish in terms of story purposes? Can the rogue accomplish things a more classically moral character cannot? Most importantly, what do authors need to do in order to help readers like the rogues, rather than just thinking they're awful people?
