Reminds me of a funny video I saw that talked about some of the most famous Japanese warlords and their depiction in media; one of the warlords is often depicted as a funny monkey man but he was a brutal war criminal who tried to invade Korea and killed tons and tons of people, and he mentioned something about the other two but I can't recall what it was exactly (I think one of them was Nobunaga who I think he said was the least worst of the bunch but still bad).

You get this simple philosophy here but the history behind the group is actually quite horrific (if I recall correctly, wikipedia even has a page just for Tibetan torture methods).
