As Sam Dresser notes, "Readers looked to Sartre and Camus to articulate what that new world might look like."
Sartre disliked Camus' approach considering it "bad faith." He felt that Communism was the best system to address the dehumanizing effects of poverty, and he was prepared to endorse violence. Sartre continued to advocate Communism until 1956, when the Soviet tanks rolled into Budapest and brutally crushed the Hungarian freedom movement. Thousands were killed and wounded and nearly a quarter-million Hungarians fled their homeland.
Though Sartre distanced himself from Soviet style Communism, he never abandoned the idea that revolutionary violence might be warranted. His commitment to violent overthrow of unjust systems became acute after the 1968 May-June student riots in France. Well into his advanced years he participated in Leftist marches, some of which turned violent. He is described by Agnès Poirier as having the "sparkle of the perpetually angry man."
