Nooo, the character is such a wretched human that you can't help but root for him.

He's being an ass in order to push people to do better, and at the end of the day (over and over again) he cares about Justice or at least the National Interest, but he cares about the Slow Horses more (in his way).

The flatulanece (et al) works as a filter: can you see past the boorishness?
