Besides, in my own little canon, Toons don't experience the same afterlife as we do. Death is only a temporary thing in the Tooniverse. Even when a character dies in a story, they're still able to show up with or without reason in other places. For that matter, their Heaven and Hell (and whatever else you can think of) is different as well and, with a few exceptions, you can come and go as you please just as you can anywhere else in the Tooniverse.
It's pretty much like death in DragonBall Z: "Oh, you're dead? Well, just take a little stroll down that long hallway and you can be alive again. Or, if you've got time to spare, wait in line to fill out a form."
The price of immortality. Is it too little to care for as you lose all true emotion, or too much to bear as your memories cause pain? One must wonder, if seeking immortality is truly worth it, and thus achieving it, is it a gift of the gods, or is it a curse of the devil himself?
