You still forgetting that scientists don’t make government policies or start wars.
I’ll grant you that the atom bombs were made by scientists and engineers, but who ordered them to be used, and who actually dropped those bombs at the Japanese cities.
Since you are determine to make science as bad guys, what about the design and construction of the motor vehicles, planes and ships. Each of these can be use for both non-military and military purposes.
Would you still demand that all planes, ships and automobiles to cease to be made even for non-military purposes?
And though nuclear fission, the “splitting of atom” was discovered in 1938, before World War II started, this discovery was never intended for military purposes.
But the nuclear physics actually started with discovery of radioactivity and radioactive decay back in 1896, so before even World War I. No one here, knew it would lead to making nuclear fission bombs, several decades later.
