Very true. Bourdain did amazing things for the idea of "authentic" travel and cuisine (yes, as authentic as you can get with a camera crew and production staff).

But he was (obviously) deeply troubled.

Parts Unknown, S6E6 - Borneo, to me, shows this the most. He is invited by a tribe to slaughter a pig for the Gawai harvest festival and says that initially he thought he might have a hard time with it. "But, I have been hardened by the last ten years", and follows it by saying that it ends up being easy and that he only feels relief when the pig finally dies, and admits "I'm not sure what that says about me".
