What enjoyment or satisfaction did Adolf Hitler really get out of "Being dictator" of Germany?

The guy had things his own way for a long time and literally got away with murdering all but a few of his perceived enemies. He gave a lot of people a good time with his expansion of industry before the war and took science into the modern era. Obviously he was deranged but he must have over achieved to the point of satisfaction and as anatheistt he had no worries and his death was so easy too.
