Dude, read your own link, Truman et al thought hard about it, and dropping two bombs was the only realistic option to end the war quickly, decisively, and with less loss of life (less than invading the islands would have caused). Imperial Japan posed a threat to the world, and they were systematically doing thousands of horrible things and needed to be shut down completely; I will not waste ink on it here but you can google it if interested.
