"Yes," she wrote later in her autobiography, "the end in this case justified the means."[165] While she never gave explicit approval of Leon Czolgosz's assassination of US President William McKinley, she defended his ideals and believed actions like his were a natural consequence of repressive institutions. As she wrote in "The Psychology of Political Violence": "the accumulated forces in our social and economic life, culminating in an act of violence, are similar to the terrors of the atmosphere, manifested in storm and lightning."[166]
