The original reason to start the project which I had―which was the Germans were a danger―started me off on a process of action, which was to try to develop […] the system in Princeton then at Los Alamos to try to make the bomb work. […] With any project like that, you continue to work trying to get success, having decided to do it. But what I did―immorally, I would say―was not to remember the reason that I said I was doing it. So that when the reason changed, which was that Germany was defeated, not the singlest thought came to my mind at all about that, that that meant now that I have to reconsider why I'm continuing to do this. I simply didn't think, okay?
