"Hopefully, I would never become somebody like that," she says.
"I'm fascinated (about playing the villain's role) because I always wonder about why serial killers kill people and can't stop. They are people like us, but for some reason, whether it is the nurture or the environment, they do things we can't even imagine. When you play a villain, that part of the storyline is very alive."
Nevertheless, not everyone enjoys playing the villain.
After his debut in Furious 7, British actor Jason Statham joins the franchise again.
Known for his image as a masculine hero on the big screen, the 50-year-old actor does not consider his role Deckard Shaw as the baddie, though he goes against the Dom's team in the last installment.
Academy Award-winning actress Helen Mirren is another debutante in this series.
Meanwhile, responding to Chinese netizens who joke that The Fast and The Furious may eventually have racing in outer space, Morgan says: "The films are big, but are not about superheroes. They are about real people in the real world."
Perhaps, the sense of reality partially explains the popularity of the series.
As Moritz says: "There is no Chinese actor in The Fast and The Furious, but Chinese audience relate to it because it is about family."
Moritz also says: "If you have themes that are relevant, the films can play worldwide."
So, will there be races in the streets of Chinese cities in the future? Morgan says: "The traffic (in Beijing) is amazing, just like Los Angeles."
