Double Subverted: That was just the story that the Emperor gave. It really is him, but he doesn't want his possession of secret resurrection Phlebotinum to be common knowledge.
Parodied: No one goes to anyone's funeral because they know they'll be alive the next day. If You Die I Call Your Stuff is thrown around like "shotgun".
Deconstructed:
A world where everyone can come back to life after death is portrayed realistically. People who really shouldn't be around anymore are back, and there's very little that can be done about it. Alternatively, the unchecked population growth of such a world leads to the collapse of society from overpopulation and struggle for resources.
Alternatively, repeated deaths result in complications, such as brain decay, leading frequently-killed characters to Take a Level in Dumbass.
Or people were allowed to come back by some form of Eldritch Abomination, and are now forced to serve it.
Reconstructed: However, the upsides are shown as well. Grandma can come back, for instance. As well, overpopulation problems can give rise to many willing explorers who go out and settle in unknown areas, leading to a new age of exploration.
Zig Zagged: That new "Emperor Evulz" is the previous one's son; but it's just a masquerade made up by Evulz. However, there are only so many times he can die and come back.
Bob: "Does anyone actually die in this series, or what?"
Carl:"Only if they're mooks."
Invoked: The Empire begins researching resurrection technology.
Defied:
The chief scientists of The Empire, who actually hated Evulz and were being forced to work under him, decide not to bring him back in the hopes that a better ruler will come about.
People turn to God (or some being of comparable power) to bring back the dead. Said being says "no" and deconstructs this trope along with a Hannibal Lecture.
Discussed: "Doesn't anyone stay dead anymore?"
Conversed: "This show can't seem to kill anybody off!"
