I thought so too at first, but after thinking about it, it doesn't make sense.

He said "Before I send you to your maker..." and "In this world, there is a place you mustn't set foot in. That place is called the underworld and you're standing at it's gates".

If he meant the afterlife he wouldn't have said "called the underworld" and "in this world".

And it wouldn't make much sense to say "Before I kill you, I'll tell you not to die".
