Cathedrals of Blood (Twilight of the Idols)

Is morality a product
Of evolutionary need
Or is it just fear and torment
Sharpened to a point by dogmatism?
Can there be true altruism
When you're looking for reward?
Can you exercise true charity
If you expect heaven's doors?
Build up your cathedrals
Upon the cornerstone soaked in blood
Your vacuous intellectual ruins
Maintained at enormous human cost
