Do you think they thought they were good guys because you watched a Hollywood movie?

EDIT: tried to take the onus off you, but as usual history is more complicated than I expected. Clearly I know nothing because I had no idea of the scope:
At its peak, it employed over 125,000 direct staff members, and probably a larger number of additional people were involved through the subcontracted labor that fed raw resources into the project. Because of the high rate of labor turnover on the project, some 500,000 Americans worked on some aspect of the sprawling Manhattan Project, almost 1% of the entire US civilian labor force during World War II.
Sooo unless you choose an arbitrary group of scientists, it seems hard. I haven’t seen Oppenheimer but I understand it carries on the narrative that he “focused on the science” until the end of the war when his conscience took over. I’ll mostly look into that…I'm not taking a stance here, but it's easy to see why many Americans believed developing the atomic bomb was a net positive at least for Americans, and depending on how you interpret it even the world.
The scientists who continued after that (not all did) must have had some other motivation at that point.
Morals are hard in real life, and sometimes really fuzzy.
Long story short they claim they thought the bomb was impossible, but it was still a large matter of concern for him as he worked on nuclear power. The most interesting tidbit was that Heisenberg was in a small way responsible for (west) Germany’s ongoing ban on nuclear weapons, which is a slight redemption arc.
Wernher vin Braun on the other hand got lauded for his contribution to space exploration. His development of the V2 and his use of slave labour in building them was somehow just a minor disgression for the, ultimately under US leadership, greater good.
Japan and the Soviet Union were more complicated issues for some of the scientists. But that's what happens with warfare. You develop new weapons, and they aren't just used for one enemy.
Say rather that he's apolitical.
"Once the rockets are up, who cares where they come down?
That's not my department, " says Wernher von Braun.
