It is interesting to me, to watch him as Host and principal of the the Nat Geo show, after seeing him in "...Wormhole" and in "narration" mode. He can be a little uncomfortably extemporaneous in "...God", and I realized I like my Morgan a tad more scripted. But the show is an interesting one, to me; plus, I have learned things, which is also good.
As to the "Golden Rule"/reciprocity angle, I think it really does boil down to trying to do ones best in whatever role or guise, and avoiding negativity and hurtfulness, whenever possible. Not that I imagine a Cosmic Ledger or anything...but I do "believe" we have the capacity for such magnificent Goodness.
Trouble is, that word, "Goodness", has so many different meanings to different people...
