Well if I just claimed "she sacrificed her reputation to help the poor" without explaining why, that will cause a lot of misunderstanding. So I will risk my ID's life to explain a little more here.
For both vacations with Doid in August, Diana had tipped off a paparazzi Jason Fraser to take intimate photo of her and Dodi on the boat, including the "kiss photo". Basically, it can be said the craziness of media fanzy on her and Dodi was orchestrated by her. Here is the article
Photographer Jason Fraser opens up on his special relationship with Princess Diana | Daily Mail Online
However, this didn't do any good to herself. Especially, Aug 14, Dodi's engaged girlfriend Kelly Fisher launched a very public lawsuit against Dodi, and sold her story to a tabloid for $200,000. And the tabloid newspaper published an interview with her and went on to serialize Fisher's story with a name "Kelly, Her Own True Story", just like "Diana, Her Own True Story" . On the night of Aug 20, when Diana came back from the holiday with Rosa, she talked to her friend Michael Barrymore for two and a half hours. She told him the affair with Dodi was serious, but did NOT say she was in love.
"She was `nervous and jittery', wanting to discuss the whole Dodi situation...There had been days of revelations since then. Diana had to give Kelly's claims serious thought. This was not like her previous romances, conducted in secret, with no one to think of but herself. This was a very public affair which could have repercussions, both for herself as a Royal figure and for her sons, one of whom would succeed to the throne" -- Michael Barrymore
It is silly to think Diana didn't know the consequence of being seen with Dodi again at this moment. With any common sense, Diana should stop this relationship with Dodi, or at least wait until things cool down and stop being seen with Dodi for a while. Otherwise it would not only damage her reputation but also embarrass her sons. Nevertheless, while there wasn't any reason to be hurry in this new relationship, at this tornado moment, she decided to go for another vacation with Dodi. In the morning of Aug 21st, she did the
Le Monde interview, and said the famous phrase "Nothing bring me more happiness than trying to help the most vulnerable people in the society." Then at the same night, she set off for the vacation.
And again she tipped off Jason Fraser to take their intimate photos, and kept him up to date about where she and Dodi could be seen.
The situation is like, someone came out claim to the world that Diana was playing a third-person role in their relationship. As a response, not only Diana didn't stop the relationship, to the contrary of anyone would expect, immediately she invited the whole world herself to see how she played this third-person role. This is like committing a reputation suicide, without even a proper reason. As such a smart PR people like her, that is really out of character.
Basically, through the whole Aug of 1997, her state of mind was to "attract as much attention as she can AT ANY COST". The question is WHY? Then we need to look at another thing she was planning at the same time. If you look at the posts started here
http://www.theroyalforums.com/forums/f38/dianas-charity-work-and-patronages-11254-5.html#post1758520, you will know that she had set a goal for herself, which was to make the Mine Ban Treaty to include strong language on rehabilitating mine victims. This was a very difficult mission. You can find out why it was difficult here
http://mercury.ethz.ch/serviceengine/Files/ISN/114666/ichaptersection_singledocument/8461edac-d626-4862-8c52-d1ad2a9050d6/en/03_Landmine+Survivors+Speak+Out.pdf. But she was very determined to achieve her goal, you can see it from her thank-you notes.
The final draft of the Mine Ban Treaty would be negotiated in Oslo, Sep 1-18, 1997, which is merely several days from her second holiday with Dodi. Although it was not easy to make policy maker changed their mind, but the mine victims were absolutely entitled to certain form of rehabilitation assistance LEGALLY. But they were too weak, too scattered, and their voice was too small to be heard. Chance was slim that their rightful interest would be appreciated if there was not a loud voice to speak for them, to attract press coverage of their stories, as what Diana said at the beginning of her speech:
"For the mine is a stealthy killer. Long after conflict is ended, its innocent victims die or are wounded singly, in countries of which we hear little. Their lonely fate is never reported ..."
In her
Le Monde interview, Diana defined her role as a "messenger". It is not that she had any political power which could single-handly change the mind of policy makers, it is because of the virtue of fact that the mine victims were completely entitled to their own right. What the victims needed was a loud voice to speak for them, to make the world notice that their legal right had been neglected. That explains why Diana would have been so adamantly trying to seek as much attention and publicity as possible before the Oslo conference. It seems she not only wanted the attention from Britain, but also from the whole world. The louder her voice was, the more people can hear the victims' voice. She was their messenger.
But in order to make her voice loud at that moment, very unfortunately, because of the Kelly Fisher's case, she had to sacrifice a great deal of her reputation. That is why I said "she sacrificed her reputation to help the poor".
Actually this is her own words to her work partner when she was in Bosnia (Aug 8-10) visiting the mine victims there,
The reporters and photographers have made my life horrible, so I would like to make their life horrible by taking them to places they normally otherwise would not visit and covering issues they normally otherwise would not cover.
