More likely he didn't trust democracy and by being radical he thought about taking the power instead of using the democracy and its institutions like elections, like the nazis were doing at that time.
He despised the nazis for killing jews and mistreating russian war prisoners. His son was sent in a suicidal mission and died because he said Germany should lose the war.
He clearly disliked the bourgeoisie and capital owners and he envisioned a different world, more like in ancient Sparta where avery many should be a hero - like he tried to be in WWI. That's why the article made references to Iliad.
He clearly sees more order in the natural world than in the world in which he lived. He wanted to see the same kind of order and reasoning in the world surrounding him, but the world surrounding him was much more absurd.
At first he was trying to change the world in a quite donquijotesque manner. Realising he can't change the world and there aren't many people with his vision and wanting to rally in that mission, he stepped out and observed the world from his refuge with the clinical interest of an enthomologist.
Later, he derived pleasure from building imaginary worlds.
