All actions have consequences. The fact that she took advantage of an ingènue (in the early years) like Diana and butted in their marriage had consequences. Although Diana was not perfect, she did do the right thing by confronting Camilla and asking her to leave Charles alone, but C did not. And of course Charles had a bigger part, but don't you think he is a bit gullible and Camilla manipulated that even more? I think she
indirectly caused her death physically, but she
directly caused the death of the marriage. And anyway if Charles just wanted a mistress in the 1st place then I think it shows that he is in no hurry to marry Camilla. I think it is condescending to Camilla to be termed a mistress. Where is the self-respect...
