The guy who spent his youth robbing banks to fund a revolution, succeeded, went on to beat the nazis, and helped lay the foundation for the greatest increase in standards of living in the modern age outside of China?

Even if you accept legitimate criticisms about the guy, such as interning/relocating populations in the wake of WWII, various loses the CPC took due to following his mandates, his failure to support Korea, etc, and understand him as a part of a greater machine accomplishing these things rather than the idealist "great man theory" nonsense that encourages hero worship in the first place, it's hard not to idealize revolutionary heros like him and Fidel.
