Why is Louis riel described as a controversial character?

Louis Riel is considered a controversial figure due to his dual role as a political leader and a rebel. He is celebrated by many Métis and Indigenous people for advocating their rights and culture, particularly during the Red River and North-West Rebellions. However, his methods, including armed resistance against the Canadian government, and his execution for treason in 1885 have led to polarized views about his legacy. While some view him as a hero and a martyr for Indigenous rights, others see him as a traitor to Canada.
