Laura, from my point of view, Alexander was more a pushover. Of course, he had the education of a great prince born in the Age of Enlightenment since his paternal grandmother Catherine trusted him to the swiss tutor Frederic Caesar de Laharpe. Laharpe followed the intellectual line traced by the men who regarded themselves from a elite with a mission: to lead the world into progress, taking away irrationality, doubtful superstition and tyranny. The old ways needed to be replaced by new ways of government.
Of course, Catherine was wise enough, or maybe pragmatical enough, to select a second tutor on Alexander: Nikolay Saltykov, a militar who had not the deep beliefs of Laharpe about love of mankind. He was choosen to teach Alexander all the traditions of Russian authocracy.
I think that Alexander was an authocrat with a truly desire of made great reforms, but this was not a new thing in the Russian story. The brief tsar Feodor III, under the influence of his polish friends, made a number of reforms. The regent Sophia Alexeyevna, with his famous advisor prince Golytsin, made a number of reforms. The tsar Peter the Great made a lot of reforms. The german friends of tsarina Anna Ivanovna or later the ministers of Elisabeth Petrovna made a good deal of reforms, too. Catherine tried to enlightened his reign. Paul tried to balanced the reforms of his hated mother reign with his own chivalric ideals. So, Russia was into a large, very large, process of reforms. Of course, Alexander took all this inheritance and go straight ahead...but always with a great support.
I believe that Alexander was seriously damaged by his childhood, when he was always emotionally torn between his grandmother (who adored him) and his father (who suffered a great jealousy to him, because it was said that old Cat wished to be succeeded not for her son, but for her grandson). Alexander became a man who needed a good deal of support. He had his entourage...all these men: Victor Kochubey, Nikolay Novosiltsev, Adam Jerzy Czartorisky, Pavel Stroganof, Mikhail Speransky... They were his "guiding lights", the candles who lighted the path to follow it. Of course, I can be wrong, but I think that without all these men encouraging him, Alexander never had done all that he done.
