To prevent him from contaminating society, from spreading meaninglessness and detachment to others, the jury found him guilty of callousness and condemned him to death for being a stranger to his mother, his lover, his friends, moral codes, social norms, and cultural conventions.
For the generation after WWII, for the survivors after the stench of Hitler and Stalin and the taste of Aushwitz, Nanjing and Hiroshima, what could be more seductive than embracing absurdity and thrashing humanity?
Nineteenth century optimism had crashed into a stonewall; utopia had metamorphosed into the Holocaust; the unlimited possibilities of reason, science and humanity had created the machine guns, the gas chambers, and the atomic bombs. Stranger, welcome to the brave new world!
Just as a starving child would ignore Zeno’s problem or Fermat’s Last Theorem, so a stranger would neglect the alien faces and tunes, desiring to smell his home soil, to shake his kinsmen’s hands and to hug his "ground of being." In an absurd world, moral, social and cultural contracts would appear frivolous and irrelevant, and those who had feasted upon absurdity may view the world with a different pair of colored glasses and appreciate the Meursault’s methodic actions and orderly world.
