It really does seem like a simple question, though it isn't, its personal.
The answer directly reflects on the person analyzing the equation ..
One's perspective is what dictates the reasoning behind the matter ..
Einstein is in the history books for a reason ..and obviously, its not the average joe that will accomplish what he did ..

1-The physicist Albert Einstein did not directly participate in the invention of the atomic bomb. But as we shall see, he was instrumental in facilitating its development.
2-But bombs were not what Einstein had in mind when he published this equation. Indeed, he considered himself to be a pacifist.
3-His position would change in 1933, as the result of Adolf Hitler's ascent to power in Germany. While still promoting peace, Einstein no longer fit his previous self-description of being an "absolute pacifist". Einstein's greatest role in the invention of the atomic bomb was signing a letter to President Franklin Roosevelt urging that the bomb be built.
Honestly he WAS a GENIUS, but in my perspective, if he was capable to put together such theories, why not analyze who (obviously) and how, and why it would be used ..
If you look down on history, wars aren't created to liberate others .. regarding Iraq, people weren't liberated once Saddam Hussein was hung .. and if the mission WAS to help, why take their oil lolz ?? (small example)
Wars are created to enforce one's personal gain .. you win, you take over ...
Is it relative to knowingly create or help create a bomb, when you can't control who and why they use it.. hell no.
So in all respects, HE is/was one of the smartest people, but no offense, I wouldn't say the direction he set his determination wise.
