That's a theme that's brought up in The Resurrection of Ra's al Ghul. Tim seriously questions why some people, like Jason, return, while everyone he loved - his father, Spoiler, Conner - stays dead. He wants to resurrect all of his loved ones, though eventually realizes it's egotistical as it's not up to him, and he would have to restore everyone's loved ones.

Well, Conner did return and Steph wasn't really dead. But his original feeling remains. Especially since Captain Boomerang, his dad's killer, did come back later.
