Well he had the lethel combination
He was pure evil but was a very clever man, the result millions of inocent people lost there life's. He benifited from the state of Germany in the 30's and nearly took over the world, because let's be honest if he hadn't of tried to invade Russia there's a very high chance we would all be speaking German right now.
He had some good ideas like Volkswagen and he cut unemployment by a great deal in Germany when he became Fuhrer, but his true intentions we're always very sinister and to a huge extent he got to enforce his intentions once he started invading Europe.
An evil evil man and a true warning from history that should never be forgotten because we can use him to never make the same mistakes again in any nation.
