yes, insaine is thrown around very loosely.
But it does apply to Adolf. Though, he also was awarded the highest military honor while in the army for leading a large number of men caught in a gas attack through enemy barrages to a hospital almost blinded from his own exposure to the gas.
Go figure...
His father was a minor civil servant with some stature in the end who was abusive and he did in fact have good artistic skills. Well enough that he would sell his painted and drawn post cards while trying to get into Art University. He worked close with some Jewish art dealers whom he considered friends, until later years when he considered them thiefs that took advantage of him. He did not really get to far into the idea of politics until the moment that he found himself recovering in the hospital from that gas attack, facing three communist germans who held rank above him and were speaking of out right revolt against Kaizer. At that moment he claimed that he knew he had to do something to right the wrongs that the Jews had placed upon patriotic Germans that died in WWI. He laid their loosing the war solidly at the Jews feet, and continued to fall deeper into that perception until his life ceased.
Much more to it, but, yes it does apply to him without a doubt.
