What are Napoleons major flaws?

Napoleon's major flaws included his ambition, which led to overreach in military campaigns, notably the disastrous invasion of Russia in 1812. His insistence on centralizing power and implementing strict control stifled political dissent, creating resentment among various factions. Additionally, his disregard for diplomatic alliances often alienated potential allies, ultimately contributing to his downfall. These traits combined to undermine his achievements and hasten the collapse of his empire.
