I read that GOLDEN AGE series and first thought, Ted Knight's breakdown over guilt from his role in the A-bomb project was modern sensibilities projected into the past. Back then, the war was real and desperate, and winning it would prevent an invasion of Japan that would take years and cost hundreds of thousands of Allied lives (and many more Japanese than that). The books I've read on the Manhattan Project didn't mention any of the scientists being outspoken about feelings of guilt.
Then I thought, you know-- Ted's characterization in the Golden Age was always a hypochondriac pretending to have fainting spells, anxiety attacks, heart palpitations and so forth. What if there was a basis to that and he really did have a borderline health issue that came out (not from morality issues) but from the letdown after the stress of working intensely on the Project? It would explain a lot.
