who said I think we'll all be destroyed by the a bombs so why should I care about anything
I have no idea. Is this something that might be in your class/text materials? It's very hard to go backwards from a quotation, much less a paraphrase, and find the author.
That was not an uncommon statement during the early days of the Cold War.
You might want to look here and see if you can find it, or something like it.
