Tearjerker: Disgaea 4: A Promise Unforgotten
The full backstory of Nemo. Born in a country torn by war, he became a young soldier skilled in fighting. Then a defeat caused his country to declare him a spy, and his family was killed before his eyes for his actions, and he was cast out. He eventually wandered to the border between countries, dying of dehydration and malnutrition where he was rescued by Artina, even though she worked at a camp of the enemy country. She brought him back to health and restored his hope, but then HER country declared her a traitor for helping an enemy, and executed. And Nemo got captured and tortured AGAIN, being forced to live despite wishing for death. This sent Nemo into the depths of despair, yet despite his anger and thirst for revenge he resisted his dark desires. But he had lost faith in God, and was unable to hear the voice of Artina who had become an angel. Eventually his hatred grew so large that his soul avoided Death even when his body had died and crumbled to dust. You just want to give the man a hug.
