"And what if I can't appreciate it anymore? What if the only part of me that lingered after death is the angry, hateful part?" he says, "What if the rest of me's deader than dead?"

After he died he only felt rage for the longest time. Then one moment of relief, and then he was here and full of rage again, and any respite from it is short-lived because other emotions make him ache for the life that was taken from him.

Anger, at least, feels just as good dead as it did alive. Maybe even a little better.
