Antigone

After Creon figures out his mistake, he will bury them all with high honors, but would he go to Elysium or the Asphodel Fields?

Elysium is the best place for souls, Aspodel Fields for neutral souls where they feel nothing, and Tartarus for the evil ones.  Just in case someone doesn't know.   ;-)

We can presume that Creon will live several mores years after the events in Antigone. So he'll have time to atone for his mistakes. I wouldn't call Creon evil. He made bad decisions, but he thought they were for the right reason. He'd probably end up in Elysium.
