The central twist of "Rashomon" is that there is no definitive resolution to the murder mystery. After the testimonies of the bandit, the wife, and the dead samurai (through a medium) all contradict one another, the woodcutter, who initially claimed only to have found the body, reveals that he witnessed the entire event. His version of the story, however, does not align perfectly with any of the others and paints all three main participants in a far less flattering light. According to the woodcutter, after the rape, the wife goaded both the bandit and her husband into a fight, calling them cowards. The ensuing swordfight was not a noble duel, but a clumsy, pathetic, and fearful struggle. The bandit ultimately kills the samurai more out of luck and desperation than skill.
However, the woodcutter's testimony is also revealed to be tainted. The cynical commoner deduces that the woodcutter did not come forward because he stole the wife's expensive dagger from the crime scene. This revelation casts a shadow over the woodcutter's entire story, suggesting that his version may also be a self-serving lie, perhaps constructed to minimize his own guilt. The film deliberately leaves the audience in a state of uncertainty, suggesting that an objective, verifiable truth is ultimately unattainable. The 'truth' of the film is not what happened in the grove, but the revelation that all humans, even a seemingly honest woodcutter, are fallible and prone to self-interest. The final scene, with the abandoned baby, shifts the film's focus from the unsolvable mystery to a question of moral action in an uncertain world. The woodcutter's decision to adopt the baby, an act of pure altruism, suggests that even if we cannot know the truth, we can still choose to do good, thus providing a sliver of hope and restoring the priest's (and perhaps the audience's) faith in humanity.
