13) Lori Grimes

Lori died during a failed C-section delivery in The Walking Dead. In season 3, Lori goes into labor during a walker attack on the prison. With no medical help available, Maggie performs an emergency C-section to save the baby. Lori knew that she wouldn't survive the procedure, but insisted on it to ensure the baby's safety. In a heartwrenching scene, Carl shoots his mom to prevent her from turning into a walker.
