Yes, using atomic bombs was bad. As others say it is debatable if it helped end the (already won?) war. And in any case, _lasting_ _piece_ where? Are middle east and Africa not part of this world?

I find your comment is entirely missing the point and low effort. Asking whether random techniques, inventions, inventors were "bad" or not makes us much sense as asking:

Is the sun bad? Were dinosaurs bad? Are the aliens bad? Is life bad?
