He refused a command to kill innocent villagers to protect his master’s ambitions, which led to his betrayal and death. Before dying, Amidamaru made a promise to his best friend and swordsmith, Mosuke, to have his damaged sword repaired. However, Amidamaru was ambushed and killed before this could happen. His regret and unfulfilled promise caused his soul to linger for 600 years near the spot of his death, unable to move on.
