Technically, from the religious point of view, God doesn't truly kill anyone. God isn't destroying the spirit, he's bringing it home.
If you truly believe this, what is the point of having a physical existence in the first place?
What an odd use of a life, time, energy and brain power, researching something you believe doesn't exist
I don't believe literally in the Norse gods but i don't see why that should preclude me from studying their mythology.
