I never really understood what they meant by the "Purgatory" thing.

Generally, Purgatory is used as a place you go when you die, a waiting room of sorts, and generally people know that they're dead, so why is Walker continuing his mission as if he's alive.

Also, if it is Purgatory, than what the hell do the ending mean/represent.
