Meursault embodies the absurd hero who is aware of life's meaninglessness yet tries to live within it. His emotional detachment, whether towards his mother's death or his girlfriend Marie's love, makes him incomprehensible and dangerous to society.

The novel demonstrates the power of social norms and expectations. Meursault's behavior, particularly his indifference to social conventions, proves fatal. His trial focuses less on the murder and more on his emotional distance and inability to show remorse.

Despite the omnipresent absurdity, Meursault searches for meaning in life. This search leads to a nihilistic realization: the only meaning lies in consciously accepting meaninglessness. In confronting death, Meursault finally finds a kind of freedom and reconciliation.
