Step-by-step explanation:
Ian Fleming, the author of the James Bond series, revised the phrase 'Live and let live' to 'Live and let die'. This phrase became famous as it is the title of the second James Bond novel and also the title of one of the James Bond movies. The revised phrase suggests a much less forgiving attitude, implying that one should go about their business without regard for what happens to others, a stark contrast to the original phrase which advocates for tolerance and coexistence.
