Final answer:
Julia's previous life details are not presented in the movie 'Defending Your Life,' hence a factual answer isn't available within the movie's context.
Step-by-step explanation:
The question about Julia's previous life in the movie Defending Your Life appears to be based on a fictional context rather than an actual philosophical or ethical issue. In the film's story, characters undergo trials to defend their actions from their past lives, but the specific details of Julia's past life are not the focus of the plot and are not expounded upon. Therefore, the question about her past life doesn't have a factual answer within the movie's narrative.
