I cannot say that I did not understand head and tail of your question because I understood only head and tail of your question. Thus I will answer very broad highlights of Congress achievements and then pointing to some documents that can give you more information if you are interested in reading. In short good and bad whatever has happened in India in terms of development and policies is done by Congress.
Sacrificed future of India Interesting ! But correct, Gandhi family sacrificed Indira Gandhi, and India has not got a stronger and brave Prime Minister like her till date.
Achievements of Congress:
Green Revolution in India
==================
Green Revolution in India transformed India from importers of food grains to exporters.
Established in the early 1960s, the Green Revolution was the unofficial name given to the Intense Agricultural District Program (IADP) which sought to insure abundant, inexpensive grain for urban dwellers upon whose support Gandhi—as indeed all Indian politicians—heavily depended. The program was based on four premises:
1) New varieties of seed(s),
2) Acceptance of the necessity of the chemicalization of Indian agriculture, i.e. fertilizers, pesticides, weed killers, etc.,
3) A commitment to national and international cooperative research to develop new and improved existing seed varieties,
4) The concept of developing a scientific, agricultural institutions in the form of land grant colleges.Lasting about ten years, the program was ultimately to bring about a tripling of wheat production, a lower but still impressive increase of rice; while there was little to no increase (depending on area, and adjusted for population growth) of such cereals as millet, gram and coarse grain, though these did, in fact, retain a relatively stable yield.
Nuclear weapons program
A national nuclear program was started by Gandhi in 1967, in response to the nuclear threat from the People's Republic of China and to establish India's stability and security interests as independent from those of the nuclear superpowers. In 1974, India successfully conducted an underground nuclear test, unofficially code named as "Smiling Buddha", near the desert village of Pokhran in Rajasthan. Describing the test as for peaceful purposes, India became the world's youngest nuclear power.
