who places no such self-limitations. During the cartoon series DuckTales, at times he would be heard saying to Glomgold, "You're a cheater, and cheaters never prosper!" Like his nephew Donald, Scrooge has also a temper (but not as a strong temper as his nephew) and rarely hesitates to use cartoon violence against those who provoke his ire (often his nephew Donald, but also bill and tax collectors as well as door-to-door salesmen). However, he seems to be against the use of lethal force. On occasion, he has even saved the lives of enemies who had threatened his own life but were in danger of losing their own. According to Scrooge's own explanation, this is to save himself from feelings of guilt over their deaths; he generally awaits no gratitude from them. Scrooge has also opined that only in fairy tales do bad people turn good, and that he is old enough to not believe in fairy tales. Scrooge believes in keeping his word—never breaking a promise once given. In Italian-produced stories of the 1950s to 1970s, however, particularly those written by Guido Martina, Scrooge often acts differently from in American or Danish comics productions. Carl Barks gave Scrooge a definite set of ethics which were in tone with the time he was supposed to have made his fortune. The robber barons and industrialists of the 1890–1920s era were McDuck's competition as he earned his fortune. Scrooge proudly asserts "I made it by being tougher than the toughies and smarter than the smarties! And I made it square!". Barks's creation is averse to dishonesty in the pursuit of wealth. When Disney filmmakers first contemplated a Scrooge feature cartoon in the fifties, the animators had no understanding of the Scrooge McDuck character and merely envisioned Scrooge as a duck version of Ebenezer Scrooge—a very unsympathetic character. In the end, they shelved the idea because a duck who gets all excited about money just was not funny enough. In an interview, Barks summed up his beliefs about Scrooge and capitalism: DuckTales In the DuckTales series, Scrooge has adopted the nephews (as Donald has joined the US Navy and is away on his tour of duty), and, as a result, his darker personality traits are downplayed. While most of his persona remain from the comics, he is notably more optimistic and level-headed in the animated cartoon. In an early episode, Scrooge credits his improved
