Really? Is Star Wars now a series where characters are "killed off"?
Star Wars films usually kill off one of the films heroes in each film.
Only counting characters who had lead or large roles as heroes in the series:
A New Hope - Killed Obi-Wan
The Empire Strikes Backs - None
Return of the Jedi - Killed off Anakin & Yoda
The Phantom Menace - Killed off Qui-Gon
Attack of the Clones - Killed off Shmi
Revenge of the Sith - Killed off Mace
The Force Awakens - Killed off Han
Rogue One - Goes without saying lol.
Only 1 of the 8 films have yet to kill off a good guy character that had significant screentime.
