I've never watched Bourdain, but from looking now it's lame to be calling him deplorable just because he didn't hate every deplorable. Not that that's what's happening here.
In another thread it was suggested he was a recovering addict and relapsed. He did seem to have a super awesome thing going. It sucks that you can get everything you've hoped for and worked towards and much more and still be unhappy. He had an 11 year old kid.
