Quite an interesting but complicated question ! I devoted 2 whole chapters of my university thesis on QV (her influence over her descendance and its consequences on European history) to but it would take me 100 pages to explain. A few points though :
- Vicky's incredible bluntness in discussing her children as mentioned above. Wilhelm's withered arm inspired her with an aversion which she never totally overcame. Fritz resigned himself to his son being handicapped but Vicky simply could not, it made her frantic. The arm is mentionned again and again in her letters to QV and she uses very harsh words.
Wilhelm probably sensed his mother's disgust and shame and must have felt humiliated and rejected. His arm remained a sore spot with him for the rest of his life.
- Vicky's personality was obviously narcissistic and her children's failings maddened her. Unlike her, Wilhelm was neither precocious nor particularly gifted. She was impossible to please. Her letters to him are full of rebukes and those to QV of complaints about him.
- Vicky was very much aware of the political implications in her marriage to Fritz. Her greatest wish was to help turning her father's liberal dream into reality. She believed that she had been sent to Prussia to produce a generation of reformers. Only, being a woman, she could play no political role in Prussia but through her husband and son. Hence her bitter disappointment when she realized that Wilhelm was not the physically and intellectually perfect heir she expected. He was not prince Albert come back to earth.
- She was firmly convinced that everything English was just best and her constant boasting of England's superiority must have annoyed Wilhelm (heir to a German throne) almost as much as it did those around her. His aggressiveness may have been a way to assert himself as a German in front of his anglophile mother. Besides, in bringing him up as an English liberal gentleman, she caused a deep confusion of nationalities in him. Hence his later ambivalent attitude toward England.
The child adored his mother and could not fail to sense that he did not come up to her wishes. He must have doubted her love for him or at least her capacity to love him as he was, with his failings and shortcomings.
- Bismarck, Vicky's sworn enemy, further embittered her relationship with Wilhelm. He had already taken advantage of her disastrous beginnings in Prussia to ostracize her and Fritz whose liberal political outlook he despised. The admiration Wilhelm felt for him as a young man was a godsend and he probably did his best to turn him against his parents. Worshipping Bismarck was certainly a way for W to anger his father and mother but, at the same time, we must consider that it was him after all and not Vicky and Fritz's liberal ideals which had achieved the making of the German empire under Prussia's lead. Willy looking up at the founder of Prussia's greatness therefore cannot be wondered at.
For those who are interested in the subject, I would recommand 2 good articles, "Kaiser Wilhelm II and his parents" by T. Kohut and "History as a family chronicle" by C.Lamar, to be found in Kaiser Wilhelm - New Interpretations by J.C.Röhl and N.Sombart.
