Reincarnated into a world of magic

Imagine this scenario. You're walking back home and you see someone about to get hit by a truck. Do you A. walk away. B. Stay and watch, or C. Save the person. Most of us wouldn't know what to do but our protagonist did what uh thought was right and saved them. That's how he ends up dead...only to be reborn into a world of magic with a gamer system.
