Why did Princess Margaret call herself the "evil sister"? Queen Elizabeth's younger sister had a rebellious spirit, did not recognise restrictions, led a glamorous lifestyle, often socialised with celebrities and allowed herself free antics. Margaret was the complete opposite of Elizabeth and thought they complemented each other perfectly. She once said: "When there are two sisters, and one of them is the queen, who should be the source of all that is honest and good, the other should be the seat of evil genius, the very evil sister." Margaret was a sort of "co-pilot" to the Queen, able to say what the monarch might have thought but could not express.
