So I have an idea for my protagonist for my writing project. He's a passenger onboard a large Blade Runner-looking spaceship to an off-world settlement. Several months before the events of the story, he accidentally kills a teenage boy in a car accident. He feels deeply ashamed, but is also desperately trying to simply forget what happened. While he saying he is heading off-world to find work, its also implied he wants to escape his guilt by leaving Earth. So he wakes up from hypersleep and the spaceship seems abandoned. Most of the rest of the story is him trying to survive the violent horrorshow that has infested the ship while learning that he can only grow past the accident and redeem himself if he confronts his past and accepts responsibility for what happened. Problem is, I'm trying to think of an he takes that would cause him to come to this realization--his turning point. Although he meets other survivors, he also spends much of the story isolated. Any thoughts on the premise are also appreciated. Total noobish gremlin here, so any advice is apprieciated.
