What theory of time travel do you subscribe to? The Lost, whatever happened, happened, single timeline? Or the Terminator, multiple diverging timelines that constantly change and crossover, creating new ones?
The times I’ve attempted to write time travel narratives, I tend to lean towards multiple diverging timelines — I enjoy the fantasy of being able to alter events. But I also really enjoy single timeline narratives (“Prisoner of Azkaban” comes immediately to mind). So really the answer is both? But if death is not an option, multiple timelines.
