I think Felix was a product of extreme wealth. I like his fun aspects but think that he could have used his creativity, intelligence and money to help more people. I don't mind his sybarritic side, as it is a good example of what you can do and get away with if you have enough money. I think it would have been better, though if he spent his family's money on educational institutions, elevating people out of the deep poverty that affected so many people in Russia. However he was extremely generous and during the war, although he was commissioned as an officer, he never joined a regiment and had no intention of fighting for Russia or the Tsarist regime that gave him all of his family's wealth. He did however conver part of the Moika palace into a hospital. I like the fact that Felix was extremely welll educated, having been to Oxford. I am sure he was loyal to his friends but I think he had a very weak personality and was indiscrete, not a good thing considering the sybarism he indulged in. He would have been one of your best bets is getting out of Russia during the revolutions, as he seemed to have the ability to charm the right people and bribe them.
