The provided text explores the character of Eren Yeager from Attack on Titan through the lens of Jean-Paul Sartre's concept of "bad faith." It explains how bad faith involves self-deception to avoid the burden of radical freedom and responsibility. While Eren initially embodies a desire for freedom, the text argues that his later actions, justified by a belief in fate and inevitability, demonstrate a slide into bad faith, effectively evading the existential responsibility for his choices, including mass murder. The analysis questions whether Eren genuinely believes he has no choice or is consciously using the idea of destiny as a shield to cope with his actions.
