There isn't much point to someone dying though, because they will come back to life after a short while. Not unless it actually sticks, for at least a decent amount of time with consequences.
In that sense, Jason's death was the only one that seems to have had lasting impact, as far as I know.
Jason died - came back to life.
Babs was in a wheelchair - got better.
Damian died - came back to life.
Cass died (at some point in old continuity) - came back to life.
Steph 'died' (at some point in old continuity) - revealed to not actually be dead
Dick 'died' - revealed to not actually be dead.
Tim 'died' - revealed to not actually be dead.
Kate died - literally came back to life 10 seconds later.
Basil died (?) - was revealed to be alive by the end of the arc
Who have I missed?
