Situational irony
Oppenheimer was raised in an ethical culture that valued freethinking, the importance of human life, independence, empirical exploration, and the significance of science. More importantly, Oppenheimer knew that science that he should never use to destroy humanity. Ironically, Oppenheimer became the first person in history to create an atomic bomb, which could destroy humanity in a blink of an eye. Consequently, Oppenheimer's innovation endangered human life because, when used, it led to mass deaths and the destruction of property.
The irony of the United States of America
Before the USA used the nuclear weapon in Hiroshima, Oppenheimer, and other scientists advised the government of the possible devastating effects of the weapon. Ironically, the US authorities disregarded the advice of the experts and went ahead to use a nuclear weapon in Japan during World War II in 1945. As a result, there were massive deaths, and the USA regretted its decision to use the atomic bomb.
Scientific progress
Scientific progress is a good thing around the globe because it makes life easier and better every time an innovation pops up. The paradox of scientific innovations is that they can lead to massive destruction of lives when misused. For instance, the memories of Nagasaki and Hiroshima are traumatic because they show what science can do if it decides to work against humanity.
