Stepan Bandera is considered Ukraine's modern-day founder and is as revered as George Washington or any of our Founders are in this country.
Sorry, you're wrong
Bandera is an idol of nationalists from Western Ukraine / Galicia, who had their roots and first taste of power with the Western Ukrainian Republic after WWI. They had a war with Poland which was also the root of their animosity towards the Poles, particularly in WWII.
Bandera (to the extent he was religious) and his Organization of Ukrainian Nationalists were Greek Catholic and emphasized Ukraine dialect, in opposition to Orthodox and Russian speakers who controlled the culture from Kiev and Odessa east. Bandera is certainly nobody's "hero" in those places.
What is really shows is how Ukraine was never really a nation, being a fragmented collection of ethnicities which fell off pre-WWI empires of Austro-Hungrary, Poland, Russia and then the Soviet Union.
And such environments are prefect for foreign intel agencies to promote and train specific, radical/ideological groups to lead among the chaos.
