Sciene has it benefitted us or had harmed us?

It can't true,u ask this question and I also answer it through internet,it is also the benefits of technology.If we want to see only the harm of science it will be wrong.Science develope a society but many peoples use it to rule over others and to destroy the harmonic peace of the society.Nuclear energy was found and can be developed for the eminence demand energy in our civilization,but many warmongers used it as a nuclear bomb,so it is not the harm of science but of man.Though there is no scientific progress man will quarell between them using the swords.
