I honestly never understood the sheer amount of interest that Diana gets, though admittedly I was 3 when it happened.
And does Diana get a pass for her own affairs because she's dead? Seems unfair to Charles and Camilla, I guess.
Charles is seen as an uncaring, aloof individual because of how he was brought up. Remember, his mother became queen because his grandfather, George VI died in 1952 due to 2 decades of stress with World War Two, Adolf Hitler, and his granduncle abdicating the British throne to marry a American.
