Well, at least Hagman had a long, multi-decade career. But, yeah, Hagman himself was pretty much an embarrassment. I read a long interview he gave, and I swear, he came across as the most ludicrously self-absorbed person I could imagine, droning endlessly about his search for inner spirituality through dope. It was so... pathetic.
And indeed he was also such a laughable hypocrite, obnoxiously and mean-spiritedly going around lambasting tobacco and tobacco smokers, while boozing and ingesting every form of dope around!
Agree, Hagman was an obnoxious jerk both on and off the screen.
