The current Real Madrid and Spain captain departed his boyhood club to join Los Blancos in 2005, but an explanation for the move was never offered, leading to speculation and allowing false stories to spread.
"I know what Sevilla is and how the fans feel," Ramos said in his documentary. "Nobody can tell me, because I've experienced it since I was young.
"All of the information was manipulated, and they lied to Sevilla. It was painful, not only for me but for my family. I'll never forgive them for the pain my grandparents went through, for my parents, who cannot return to Sevilla's stadium.
"It's the biggest pain that I've felt. That's why I've acted with rage and with anger when I've played and scored there, because of everything my family have suffered."
Despite the problems that came from his move, Ramos has no regrets about the decision he made.
"I'd make the same decision a thousand times over, but I'd never let anyone tell the story that was told at the time," Ramos said.
