Anyone else feel like Hamlin is the most tragic character in the whole series

I just feel like he never really did anything to anyone except maybe moving Kim to a different office for losing clients.

He always seemed like a nice guy who was genuinely nice to those around him. Cared about Chuck and even continually extended olive branches to Jimmy over and over and over again.

Rewatching the series now, I still don't understand Jimmy's fascination with trying to ruin his life. It never made sense to me, and I'm not sure if the motivation was ever really given to the audience clear enough.

He single handedly ruined this entire guys life and tortured him continuously over the course of the show. Humiliating him at every turn.
