That's what you would think. But rereading Dilbert comics from quite far back and knowing what Adams came out with, it seems maybe that was just projection on our part. Adams probably rooted more for the psychopath dogbert, or even characters like the CEO. The most glorious thing in the world to Adams, seen both in action, in his celebrity crushes and openly in his less ironic writings, was to be an asshole and getting away with it. In that sense he was a genuine troll.
But like everyone, he didn't get away with it. In his case, not even relatively speaking, since as others have said he probably shortened his life by embracing contrarian "medicine", and probably didn't make himself happy for long with his pivot to open scorn and loathing.
