The short story 'The Spider's Thread' by Ryunosuke Akutagawa depicts a fascinating moral dilemma. Kandata, a notorious criminal suffering in Hell, gets a chance at salvation when Buddha notices a single act of kindness he once showed. A spider's thread descends from Heaven, offering him escape.
As Kandata climbs, he selfishly considers cutting the thread to prevent others from following. This moment of greed causes the thread to snap, returning him to Hell. The narrative beautifully contrasts Buddhist compassion with human weakness, showing how one's own ego can destroy opportunities for redemption.
