Prince George did lead a scandalous life, but he was very kind to his younger brother, George V and Queen Mary's youngest child, Prince John (1905-1919). John lived his short life in a cottage on the Sandringham estate in Norfolk, attended by caregivers, as he suffered from epilepsy and developmental delays. It was said that the other members of the Royal Family were "frightened and ashamed" of John's illness, but Prince George (the next oldest) visited often. So Prince George wasn't all "bad". On occasion, he was a prince.

George V only allowed his five sons to wear kilts or sailor suits as children, hence the get-ups.
